BIS(TRIMETHYLSILYL)CHLOROMETHANE Chemical Properties,Uses,Production
Physical properties
bp 57–60°C(15 mmHg); flash point 48 °C; d 0.892 gmL?1 (25 °C).
Uses
Silane, 1,1-(Chloromethylene)bis[1,1,1]- trimethyl- can be used as versatile C1 building block; broad application in Peterson olefination reactions; Grignard reagent participates readily in Kumada cross-coupling reactions with aryl and vinyl halides; useful in synthesis of methylenephosphine analogs and as sterically demanding ligand for a number of main group and transition metal complexes.
Preparation
a convenient one-pot procedure has been developed by Kemp and Cowley in which trimethylsilylchloride reacts with dichloromethane in the presence of nBuLi at ?110°Cto give bis(trimethylsilyl)dichloromethane.1 This intermediate is sequentially treated with nBuLi and ethanol to yield chlorobis(trimethylsilyl)methane. A number of other syntheses have been described
