Diphenyl[2-(phenylsulfonyl)propan-2-yl]-λ5-phosphanethione
نویسنده
چکیده
The title compound, C(21)H(21)O(2)PS(2), was obtained from the corresponding dilithio methandiide by treatment with iodo-methane. The bond lengths and angles deviate considerably from those in the dimetallated compound. These differences are most pronounced in the PCS backbone. While the title compound features C-P and C-S distances of 1.9082 (17) and 1.8348 (17) Å, respectively, the dianion showed C-P(av) distances shortened by 11% [1.710 (4) Å] and C-S distances shortened by 12% [1.614 (3) Å]. Additionally, the P-C-S angle experiences a contraction by methyl-ation of the dianion from 121.4 (2) to 111.96 (9)° in the title compound.

The title mol-ecule, C(17)H(20)O(3)S, displays a U-shaped structure; the two benzene rings are nearly parallel and partially overlapped to each other, the dihedral angle and centroid-to-centroid distance being 15.0 (2)° and 3.723 (2) Å. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules, forming supra-molecular chains running along the a axis.

In the title compound, C(35)H(30)N(4)P(2), the diphenyl-phosphanyl and diphen-yl(2-pyridyl-imino)-λ(5)-phosphanyl groups are attached to the central methyl C atom with a P-C-N angle of 114.09 (16)°. The mol-ecules stack along the b axis and inter-connect through C-H(pyrid-yl)⋯N(pyrid-yl) inter-actions, forming an infinite chain structure. The parallel chains are further inter-connected via C-H(...

The title compound, C19H17PS2, results from the direct deprotonation of di-phenyl-methyl-phosphine sulfide and subsequent reaction with diphenyl di-sulfide. The C-P and C-S bond lengths of 1.8242 (18) and 1.8009 (18) Å, respectively, of the central P-C-S linkage are comparable to those found in the sulfonyl analogue, but are considerably longer than those reported for the dimetallated sulfonyl ...

The title compound, C24H21ClN2O, crystallizes with two unique mol-ecules in the asymmetric unit. In each mol-ecule, the central imidazole ring is substituted at the 2-, 4- and 5-positions by benzene rings. The 2-substituted ring carries a Cl atom at the 4-position. One of the imidazole N atoms in each mol-ecule has a propan-2-ol substituent. In the crystal, a series of O-H⋯N, C-H⋯O and C-H⋯Cl h...

In the title compound, C34H28N2S2, the central imidazole ring (r.m.s. deviation = 0.0015 Å) forms dihedral angles of 55.7 (3), 17.94 (11) and 86.27 (11)°, respectively, with the mean planes of the attached thienyl and two phenyl substituents. The thienyl ring shows ring-flip disorder [occupancy ratio = 0.647 (2):0.353 (2)]. The chiral centre maintains the S configuration of the l-phenyl-alanino...
