Dehydrochlorination of chloroform by N-methyl-N,N-bis(silatranylmethyl)amine

摘要

N,N-Bis(silatranylrnethyl)methylamine 1 reacts with chloroform resulting in amine hydrochloride 2 and dichlorocarbene. The formation of the latter was proved by a cyclopropanation reaction and insertion into the Si-H bond. In the presence of cyclohexene, compound 2 and 7,7-dichlorobicyclo[4. 1.0]heptane are the major reaction products. Compound 2 and 1 -dichloro-methylsilatrane were isolated upon the reaction of amine 1 with chloroform and 1-hydro-silantrane.
