Abstract
|
|
|
|
From the reaction of phenyltrimethylsilylacetylene with lithium, 1,4-bis(trimethylsilyl)-2,3-diphenyl-1,4-butadene dianion was formed. The reaction of dianion with dichlorodimethylsilane affords 1,1-dimethyl-2,5-bis(trimethylsilyl)-3,4-diphenyl-1-silacyclopenta-2,4-diene. In addition 1,4-bis(trimethylsilyl)-2,3-diphenyl-1,3-butadiene was isolated. It seems to be hydrolized product in alkali medium.
