BIS(TRIMETHYLSILYL)CHLOROMETHANE C화학적 특성, 용도, 생산
물리적 성질
bp 57–60°C(15 mmHg); flash point 48 °C; d 0.892 gmL?1 (25 °C).용도
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.제조 방법
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 describedBIS(TRIMETHYLSILYL)CHLOROMETHANE 준비 용품 및 원자재
