A oven-dried ground test tube, which was equipped with a magnetic stir bar and fitted with a rubber septum, was charged with (R)-tert-butanesulfinamide (0.121 g, 1.0 mmol), Pd2(dba)3 (0.018 g, 0.02 mmol; dba is dibenzylideneacetone), 2-di-tert-butylphosphino-2',4',6'-triisopropylbiphenyl (0.0212 g, 0.05 mmol) and NaOH (0.08 g, 2 mmol). The vessel was evacuated and backfilled with argon three times, then 4-biphenyl bromide (1.3 mmol), toluene (10 ml) and degassed water (0.3 ml) were added via syringe. The solution was stirred at 90°C for 20 h. The reaction mixture was then cooled to room temperature, quenched by water, and extracted with chloroform (20 ml) for twice. The organic layers were combined, and dried over anhydrous sodium sulfate and filtrated. The filterate was condensed under vacuum. The residual was purified with silica gel δ (ppm): 7.49–7.29 (m, 7H), 7.06 (d, J = 8.5 Hz, 2H), 6.03 (d, J = 3.9 Hz, 1H), 1.37 (s, 9H). 13C NMR (300 MHz, CDCl3), δ (ppm): 114.6, 140.4, 135.6, 128.6, 127.9, 126.8, 126.6, 118.4, 56.5, 22.4. FT—IR (KBr) (cm-1): 3453, 3252, 2926, 1610, 1519, 1485, 1386, 1305, 1286, 1268, 1228, 1191, 1057, 912, 880, 838, 767. [α]D = -110.8 (c 0.15, ethyl acetate). ESI-MS (negative mode), m/z = 272 [M—H]-.

with a solution of petroleum ether and ethyl acetate (5:1 v/v) as to give the title compound (R)-N-(4-biphenyl)-tert-butanesulfinamide. A test tube containing a petroleum ether and ethyl acetate (1:1 v/v) solution of the title compound was covered with a piece of filter paper and placed motionless at room temperature, and a single-crystal was cultured in the bottom of the test tube. Spectroscopic analysis: 1H NMR (300 MHz, CDCl3),All H atoms were positioned geometrically and refined using a riding model, with N—H = 0.86 Å, C—H = 0.93–0.96 Å, and with Uiso(H) = 1.2 Ueq(C, N) or 1.5 Ueq(C) for methyl H atoms.

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. |

Sulfinamides, especially chiral sulfinamides, are an important class of organic compounds in modern organic chemistry, and a great number of such compounds have been synthesized. In our continuous study on chiral N-aryl-tert-butanesulfinamides (Sun et al., 2012), we have prepared the title compound and report its crystal structure herein.
In the molecule of the title compound (Fig. 1) the aromatic rings of the biphenyl are tilted to form a dihedral angle of 38.98 (8)°, which is comparable to the value observed in other related compounds containing the biphenyl group (Jasinski et al., 2012; Gainsford et al., 2011). In the crystal packing (Fig. 2), the molecules are linked by intermolecular N—H···O hydrogen bonds (Table 1) into one-dimensional chains running parallel to the the a axis.
