HONG, JH HAN, JS LEE, GH JUNG, IN 2024-01-21T23:05:38Z 2024-01-21T23:05:38Z 2021-09-02 1992-10-06 0022-328X https://pubs.kist.re.kr/handle/201004/146372 Flash vacuum pyrolysis of bis(trimethylsilylmethyl)methoxysilanes was found to be an efficient route to 1,3-disilacyclobutanes. Flash vacuum pyrolysis of bis(trimethylsilylmethyl)dimethoxysilane or bis(trimethylsilylmethyl)chloromethoxysilane gave 1-methoxy-1,3,3-trimethyl-1,3-disilacyclobutane or 1-chloro-1,3,3-trimethyl-1,3-disilacyclobutane, respectively. The thermolysis is regarded as proceeding through initial beta-elimination of trimethylmethoxysilane followed by intramolecular cyclization of the resulting 2-methoxy-4,4-dimethyl-2,4-disilapent-1-ene or 2-chloro-4,4-dimethyl-2,4-disilapent-1-ene to give the products.
