Auto-association in organometallic compounds: a nuclear magnetic resonance study of methylcadmium alkoxides

Abstract

Cadmium chemical shifts and coupling constants have been measured for a series of methylcadmium alkoxides and aIkanethiolates using ¹H, ¹H-{¹¹¹Cd}, and ¹H{¹¹³Cd} n.m.r. spectroscopy. The results are consistent with all the alkoxides having the same tetrameric structure. Evidence is also presented that the less sterically hindered alkoxides equilibrate slowly to form higher oligomers which are probably hexamers.
