Abstract

Silylboronic esters bearing a dialkylamino group on the silicon atoms reacted with 1, 3- dienes in the presence of a palladium catalyst to give silacyclopent-3-enes (ie, 2, 5- dihydrosiloles) in high yields via efficient silylene transfer from the silylboronic ester to the 1, 3-dienes. The [4+ 1] cycloaddition was applicable to the parent 1, 3-butadiene and various mono-, di-, and trisubstituted 1, 3-dienes having silyloxy, cyano, and ester groups. ...
