Tricyclo[3.3.1.03,7]nonane-3,7-diyl bis(methanesulfonate)

S. Ioannou, A. V. Nicolaides and M. J. Manos

Abstract top

The crystal structure of the title compound, C11H18O6S2, was determined to investigate the effect of the eclipsed mesyl groups on the bond length of the vicinal quaternary C atoms. The two quaternary C atoms of the noradamantane skeleton and the two O atoms to which they are connected all located essentially in the same plane [maximum deviation 0.01 Å], resulting in an eclipsing conformation of the C-O bonds. The C-C bond of the quaternary C atoms is 1.597 (3) Å is considerably longer than the other C-C bonds of the molecule.

Experimental top

Synthesis of tricyclo-[3.3.1.03,7]nonane-3,7-diyl dimesylate (1). To a solution of tricyclo-[3.3.1.03,7]nonane-3,7-diol (1.00 g, 6.49 mmol) in pyridine (10 ml), mesyl chloride (CH3SO2Cl)(5.02 ml, 65 mmol) was added slowly with stirring at ambient temperature. The mixture was then heated at 120 oC for 5 h. After cooling, crushed ice (100 g) was added and the mixture extracted with CH2Cl2 (5 x 20 ml). The combined organic phase was washed with 2M HCl (2 x 40 ml), H2O (2 x 20 ml), saturated aqueous NaHCO3 (2 x 20 ml), and dried (Na2SO4). After filtration and removal of the solvent under reduced pressure, a brown solid (1.92 g, 96%) was isolated. Recrystallization from THF/hexane afforded pure 1 (1.71 g, 85%) as colorless crystals m.p. 127–128 oC. Elemental analysis (%): Calculated for C11H18O6S2: C,42.6; H, 5.8; O, 30.9; S, 20.7.

Refinement top

The H atoms were positioned with idealized geometry and refined using a riding model with Uiso(H) = 1.2 or 1.5 (methyl H atoms) of Ueq(C).

Special details top

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.
