Exchange in alkylzinc alkoxides and alkylcadmium alkoxides

Abstract

Coupling of ^lllCd and ^ll3Cd to both the methyl and alkoxyl protons has been observed in the proton magnetic resonance spectra of methylcadmium alkoxides. P.m.r. spectrometry has also been used to investigate the exchange reactions of methylcadmium and alkylzinc alkoxides. In particular exchanges between Me₂Cd and MeCdOR (R = Me, Et, Pr, and Ph), between R₂Zn and RznOR? (R = Me, Et; R' = Me, Et, Pr, and Bu^t), and between Me₃Al and MeZnOR' (R' = Et, Pr, and Bu^t), have been examined.
