Abstract

Stirring a benzene solution of a diorganozinc compound with an insoluble alkali metal alkoxide (MeOK or MeONa) or potassium amide (PhN(Me)K) formed asolution containing a species having a salt : R2Zn composition of 1:2. A salt (t-BuOK) that is soluble in benzene also forms a 1:2 species and, when the salt to R2Zn ratio is sufficiently high, forms a 1:1 species. Controlled heating at reduced pressure of solutions prepared from an alkali metal alkoxide and an excess of a diorganozinc compound leaves materials with alkoxide : R2Zn ratios of 1:2 or 1:1. Reactions of benzene solutions of diorganozinc compounds with (p-MeC6H4)SK or Ph2PK form solutions of composition R3ZnK.
