Abstract
Interaction of PdCl2 in chloroform with bis(phosphine sulfides) Ph2P(S)‒X‒P(S)Ph2 (X‒CH2, C(CH3)2, CH2CH2, NH, S, and SCH2S) has been studied. Mechanism of the reaction has been found to vary dramatically with the identity of X. The structures of the resultant complexes were evaluated by UV and IR spectroscopy. Crystal structures were were determined by X-ray diffraction for two of the compounds (A: [Ph2P(S)‒(CH2)2‒P(S)Ph2]PdCl2 · CH3CN, P21/n, Z = 4, a = 10.104(2), b = 20.939(4), c = 14.034(3) Å, γ = 102.54(2)· B: [Ph2P(S)‒N‒P(S)Ph2]2Pd · 2CHCl3, Pl, Z = 1, a = 9.539(1), b = 12.333(3), c = 12.866 Å, α = 111.83(2)°, β = 96.70(3)° γ = 99.84(3)°).
