Abstract

Abstract: Silylation of C3Li4 with trimethylchlorosilane is very slow in THF at 0 OC. Reaction of C3Li4 with a tenfold excess of both trimethylchlorosilane and diethyl sulfate resulted in formation of the triethylated, monosilylated derivative, Et3C-C= C-SiMe3 as the major product. Derivatization of C3Li4, MeC3Li3, and Me2C3Li2 with diethyl sulfate and trimethylchlorosilane in various orders of addition have been studied. and the results are ...
