Preparation and some properties of lead thiolates

Abstract

The preparation of a representative series of lead thiolates, Pb(SR)₂(R = Et, Buⁿ, Bu^t, Ph, p-C₆H₄Me, o-C₆H₄Me, p-C₆H₄Cl), is reported. Thermal decomposition of these thiolates leads to the formation of lead sulphide and the organic sulphide, R₂S. Reaction of the thiolates with sulphur (or selenium) gives lead sulphide (or selenide) and the organic disulphide, R₂S₂. An assessment of the stability of lead thiolates in common organic solvents is given.
