η3-Trimethylsilyallyltitanium compound, (η5-C5H5)2Ti(η3-1-trimethylsilylallyl), reacts with aldehydes to give (±)-(R,S)-3-trimethylsilyl-4-hydroxy-1-alkenes in excellent yields, which can be deoxysilylated to either E- or Z-1,3-dienes.
η 3 -Trimethylsilyallyltitanium化合物,(η 5 -C 5 H ^ 5)2的Ti(η 3 -1-trimethylsilylallyl),与醛进行反应,得到(±) - (R,S)-3-三甲基甲硅烷基-4-羟基-1- -烯烃具有优异的收率,可以将其脱氧甲硅烷基化为E-或Z-1,3-二烯。
