Synthese D#x2032;Aryl-1 Ou Alcenyl-1 Dimethyl-3,4 Silacyclopentadienes-2,4 (Siloles)

摘要

The synthesis of 1-silacyclopenta-2,4-dienes (siloles) by decomposition under mild conditions of N-phenylcarbamates derived from 3,4-dimethyl-1-silacyclopent-4-ene-3-ols has been extended to heterocycles with phenyl or allyl substituents on the silicon atom. The new siloles are trapped as maleic anhydride adducts or iron tricarbonyl complexes.
