N.M.R. Studies of Phosphine Adducts of Mercury and Cadmium Xanthates and Halo Xanthates: Crystal and Molecular Structures of Cd(S₂COPrⁱ)₂PPh₃, Hg(S₂COPr^I)₂PPh₃ and Hg(S₂COPr^I)₂p(c-C₆H₁₁)₃

Abstract

Phosphorus-31, cadmium-113 and mercury-199 n.m.r. techniques have been used to study adduct formation, in solution, between phosphines and cadmium and mercury xanthates and halo xanthates. The crystal structures of the 1:1 phosphine adducts Cd (S₂COPrⁱ)₂PPh₃, Hg(S₂COPrⁱ)₂PPh₃ and Hg(S₂COPrⁱ)₂P(c-C₆H₁₁)₃ have been determined.
