The Wittig reaction to synthesize olefins is a very attractive method in organic synthesis. Recently, this methodology has been achieved utilizing simple metal catalysts and diazo compounds in addition to a phosphine and an aldehyde. The following work investigates the use of a variety of metallophthalocyanines (MPc’s) to catalyze Wittig-like reactions from ethyldiazoacetate. We also examine the influence of substitution on the aromatic ring of the aldehyde as well as various phosphines, arsines and antimony complexes. We have been able to exclusively synthesize the trans-olefins in excellent yields in short periods of time (1 h).

金属酞菁催化醛的烯化

Wittig反应合成烯烃是有机合成中非常有吸引力的方法。最近，除了膦和醛以外，还利用简单的金属催化剂和重氮化合物实现了这种方法。以下工作研究了各种金属酞菁（MPc's）催化重氮乙酸乙酯产生的类似Wittig的反应。我们还研究了取代对醛以及各种膦，a和锑配合物的芳环的影响。我们已经能够在短时间内（1小时）以优异的收率独家合成反式烯烃。
