专利汇可以提供Organoaluminum compounds and their preparation专利检索，专利查询，专利分析的服务。并且Organoaluminum compounds possessing a vinylic aluminaoxacyclopentane moiety are described. They are prepared by reacting a nonionic organoaluminum compound possessing an aluminacyclopentene moiety with an aldehyde or ketone in the presence of a stable Lewis base. The compounds possessing the vinylic aluminoxacyclopentane moiety yield on hydrolysis olefinically unsaturated alcohols. Oxidation of the moiety followed by hydrolysis yields olefinically unsaturated diols.，下面是Organoaluminum compounds and their preparation专利的具体信息内容。
