Titanocene-catalyzed double silylation of dienes and aryl alkenes with chlorosilanes
摘要:
Double silylation of 1,3-butadienes with chlorosilanes was found to proceed by using titanocene dichloride as the catalyst in the presence of "BuMgCl, giving rise to 1,4-disilylated 2-butenes in good yields. Aryl substituted alkenes also afforded 1,2-disilylated products under similar conditions. (C) 1998 Elsevier Science Ltd. All rights reserved.
