chloride and trimethyltindibromomethylmagnesium chloride reagents. Reactions of these lithium reagents with trimethylchlorosilane, trimethyltin chloride, mercuric halide, dimethyl sulfate and water are described. The action isopropylmagnesium chloride in THF on trimethyl(dibromomethyl)silane, trimethyl(diiodomethyl)silane and bis(trimethylsilyl)dibromomethane led principally to reduction to the respective

1,2-Dihalocyclopentenes on reaction with alkalimetals and chlorotrimethylsilane in hydrocarbon or ether solvents produce silylated 1-pentynes by ring opening. Sodium metal and hydrocarbon solvents favour the cleavage most. Different mechanistic aspects are considered.
