STUDIES ON ORGANOSILICON REACTIVE INTERMEDIATES (Ⅴ)~*——STEREOSPECIFIC ADDITION OF CYCLOPROPYLPHENYLSILYLENE TO OLEFINS

摘要

This paper reports that cyclopropylphenylsilylene (1) is obtained by photolysis of 2-cyclopropyl-2-phenylhexamethyl-trisilane. 1 added stereospecifically to cis-and trans2-butene gives the corresponding siliranes. Opening of the sillranes by methol also occurs in stereospecifically cis fashion.
