The 1-vinylpyrrolidin-2-one ligand in the title compound, [Ru(C6H9NO)(C18H15P)2(CO)], coordinates to the Ru0 atom with the olefin double bond and the ketone O atom. The Ru0 atom adopts a distorted trigonal–bipyramidal coordination geometry, with the C≡O ligand and the ketone O atom occupying the axial positions. The two triphenylphosphane ligands are cis to each other. The olefinic C=C bond is almost coplanar with the Ru0 atom and the two P atoms (maximum deviation of 0.0516 Å from the mean plane defined by the five constituent atoms). The coordinated C=C bond has a length of 1.449 (3) Å, which is significantly longer than that of a free C=C bond (1.34 Å). There are two C—H⋯π interactions involving neighbouring phenyl rings in the molecule. In the crystal, molecules are linked via two further C—H⋯π interactions.

To a solution of RuH2(CO)(PPh3)3 (0.40 g, 0.44 mmol) in toluene (20 ml) and under a nitrogen atmosphere was added N-vinyl-2-pyrrolidone (0.40 ml, 3.6 mmol). The reaction mixture was then refluxed for 1 h to give a yellow solution. After filtration, the filtrate was concentrated to ca. 1 ml under reduced pressure. 20 ml n-hexane were added to the residue with stirring to give a yellow solid. The solid was collected by filtration, washed with n-hexane and diethyl ether, and dried under vacuum [Yield: 0.24 g, 72%]. Yellow block-like crystals, suitable for X-ray analysis, were obtained by layering a dichloromethane solution of the title compound with hexane.
The H atoms were included in calculated positions and treated as rding atoms: C—H = 0.95, 0.99, 0.99 and 1.00 Å for phenyl, pyrrolidone, CH2 and CH H atoms, respectively, with Uiso(H) = k × Ueq(C), where k = 1.5 for pyrrolidone H atoms, and = 1.2 for other H atoms. In the final difference Fourier map the highest and lowest residual electron density peaks were 0.94 and 0.92 Å, respectively, from atom Ru1.
Ortho-alkylation of acetophenone with vinyl
via ruthenium catalyzed C—H activation has been reported by (Murai et al., 1993) Cylometallation of the aromatic ketone with the catalytically active ruthenium(0) species, Ru(CO)(PPh3)3, generated from dehydrogenation of RuH2(CO)(PPh3)3, is proposed as the key step (Murai et al., 1993). On exploring the feasibility of cyclometallation of N-vinyl-2-pyrrolidone with the ruthenium hydride complex RuH2(CO)(PPh3)3, the title compound was obtained instead of the cyclometallated product.The molecular structure of the title compound is illustrated in Fig. 1. The N-Vinyl-2-pyrrolidone ligand is bound to the ruthenium(0) center via the olefin double bond (C6═C7) and the ketone O atom (O2). The ruthenium(0) atom, Ru1, adopts a distorted trigonal bipyramidal coordination geometry with the carbonyl ligand (C1═O1) and the ketone O atom, O2, occupying the axial positions. The two triphenylphosphane ligands are cis to each other. The olefin C6═C7 double bond is almost coplanar with atom Ru1 and the two P atoms (P1 and P2), as reflected by the small mean deviation of 0.0516 Å from the mean plane defined by the five constituent atoms.
The Ru1—C6 and Ru1—C7 bond distances (2.127 (2) and 2.157 (2) Å, respectively) are similar to those reported for related olefin coordinated ruthenium complexes, such as Ru(η2-o-acetylstyrene-O)(CO) (PPh3)2 [2.121 (8) and 2.167 (9) Å; Lu et al., 1998], and Ru(PPh3)3(CO)(C2H4) [2.199 (8) and 2.213 (10) Å; Jazzar et al., 2001]. The C6—C7 bond length of 1.449 (3) Å is significantly longer than that for a free olefinic double bond [1.34 Å; Orpen et al., 1989], but is typical for a coordinated C═C double bond, for example as in Ru(η2-o-acetylstyrene-O)(CO)(PPh3)2 [1.43 (1) Å; Lu et al. 1998] and Ru(PPh3)3(CO)(C2H4) [1.451 (11) Å; Jazzar et al. 2001].
There are two C-H···π interactions involving neighbouring phenyl rings in the molecule, and in the crystal, molecules are linked via two further C-H···π interactions (Table 1).

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Ortho-alkylation of acetophenone with vinyl silanes via ruthenium catalyzed C—H activation has been reported by (Murai et al., 1993) Cylometallation of the aromatic ketone with the catalytically active ruthenium(0) species, Ru(CO)(PPh3)3, generated from dehydrogenation of RuH2(CO)(PPh3)3, is proposed as the key step (Murai et al., 1993). On exploring the feasibility of cyclometallation of N-vinyl-2-pyrrolidone with the ruthenium hydride complex RuH2(CO)(PPh3)3, the title compound was obtained instead of the cyclometallated product.
The molecular structure of the title compound is illustrated in Fig. 1. The N-Vinyl-2-pyrrolidone ligand is bound to the ruthenium(0) center via the olefin double bond (C6═C7) and the ketone O atom (O2). The ruthenium(0) atom, Ru1, adopts a distorted trigonal bipyramidal coordination geometry with the carbonyl ligand (C1═O1) and the ketone O atom, O2, occupying the axial positions. The two triphenylphosphane ligands are cis to each other. The olefin C6═C7 double bond is almost coplanar with atom Ru1 and the two P atoms (P1 and P2), as reflected by the small mean deviation of 0.0516 Å from the mean plane defined by the five constituent atoms.
The Ru1—C6 and Ru1—C7 bond distances (2.127 (2) and 2.157 (2) Å, respectively) are similar to those reported for related olefin coordinated ruthenium complexes, such as Ru(η2-o-acetylstyrene-O)(CO) (PPh3)2 [2.121 (8) and 2.167 (9) Å; Lu et al., 1998], and Ru(PPh3)3(CO)(C2H4) [2.199 (8) and 2.213 (10) Å; Jazzar et al., 2001]. The C6—C7 bond length of 1.449 (3) Å is significantly longer than that for a free olefinic double bond [1.34 Å; Orpen et al., 1989], but is typical for a coordinated C═C double bond, for example as in Ru(η2-o-acetylstyrene-O)(CO)(PPh3)2 [1.43 (1) Å; Lu et al. 1998] and Ru(PPh3)3(CO)(C2H4) [1.451 (11) Å; Jazzar et al. 2001].
There are two C-H···π interactions involving neighbouring phenyl rings in the molecule, and in the crystal, molecules are linked via two further C-H···π interactions (Table 1).
