Zerovalent platinum chemistry. Part VI. The reactions of bis- and tris-triphenylphosphineplatinum(0) with hydrogen sulphide, hydrogen selenide, sulphur, and related molecules

Abstract

The reactions of Pt(PPh₃)_n(n= 2 or 3) with H₂M, HMPh, and M (M = S or Se) to form adducts have been studied. The reactivity of the products towards soft and hard reagents has been investigated and compared with that of related H₂M, HMPh, and M adducts of some Rh^I and Ir^I triphenylphosphine complexes. The results agree with the proposed mechanisms of poisoning of metal surfaces by species such as H₂M or M.
