Reaction of Ti(O-i-Pr)4/2 i-PrMgBr, synthetic equivalent of practical Ti(II) reagent, with propargyl halides or propargyl alcohol derivatives affords allenyl titanium compounds in excellent yields, thus providing an efficient and practical method for synthesis of both allenyl and homopropargyl alcohols by the successive treatment with aldehydes or ketones.
的Ti的反应(OI-PR)4 /2 I-PrMgBr,实用的Ti(II)试剂的合成等价物,与炔卤或炔丙醇衍生物,得到丙二烯基的钛化合物以优良产率,从而提供一种有效的,实用的方法的合成烯醛和高炔丙醇均需通过醛或酮的连续处理。
