Abstract

The synthesis, and characterization by nuclear magnetic resonance (NMR) spectroscopy, of two cyano-substituted 1, 3-disilacyclobutanes, 1, 3-dicyano-1, 3-dimethyl-1, 3- disilacyclobutane,[Si (CN)(Me) CH2] 2, and 1, 1, 3, 3-tetracyano-1, 3-disilacyclobutane,[Si (CN) 2CH2] 2, are reported. Evidence for a trans/cis exchange process in solution was obtained in the case of [Si (CN)(Me) CH2] 2, where the initially obtained all-trans isomer ...
