ALCOHOL BEARING VINYLSILYL GROUP

摘要

NEW MATERIAL:Title compound of formula I [R1 is lower alkyl; R2 is -(CH2)m- where m is 3 - 10 and these alkylenes may be substituted with lower alkyl and/ or phenyl; n is 1 - 3]. EXAMPLE:4-(Dimethylvinylsilyl)-butanol. USE:Starting material of high-performance electron-sensitive material useful for manufacturing high-density integrated circuits, hologram memories. PREPARATION:For example, the hydroxly group in chlorohydrin of formula II (mis 4 - 10) is protected with a groups stable against Grignard reagents as trimethylsilyl group to form a compound formula III, which is reacted with Mg to prepare the Grignard reagent. Then a chlorosilane of formula IV is reacted with the Grignard reagent and simultaneously trimethylsiloxy group is hydrolyzed to produce the objective compound of formula I including formula V (m is 1 - 10).
