BIS(TRIMETHYLSILYL)CHLOROMETHANE Chemical Properties,Usage,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.

Uses

Chlorobis(trimethylsilyl)methane can be used as a reagent for the preparation of:

Para-bis(trimethylsilyl)ethylstyrene (PBTES) monomer, which is used to synthesize corresponding network polymer of styrene.
Bis(trimethylsilyl)methyl magnesium chloride (Grignard reagent), which is used in the synthesis of bis(trimethylsilyl) allyl compounds by reacting with alkenyl bromide via the Kumada coupling reaction.
N-[Bis(trimethylsilyl)methyl]heterocumulenes.

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
