Diphenyl[2-(phenyl-sulfon-yl)propan-2-yl]-?(5)-phosphane-thione.

ABSTRACT: 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.
