卡宾的过渡金属配合物是一个十分活跃的研究领域,有关它们的制备方法及性质的研究工作正日益引起人们的注意。Burkhardt等发现,卡宾的钨配合物能与Witting试剂反应,生成烷氧基取代烯烃。本文将卡宾的钨配合物进一步用于与二氯甲基Wittig试剂的反应,合成1,1-二氯-2-烷氧基烯烃。众所周知,1,1-二卤代烯烃是一类产生不饱和卡宾的前体化合物。因此,通过对卡宾的钨配合物与二氯代Wittig试剂之间的反应研究,还可以为进一步研究烷氧基取代不饱和卡宾的性质提供方便。 Carbene transition metal complexes is a very active field of research, the preparation of their methods and properties of the research is increasingly drawing people’s attention. Burkhardt et al. Found that the carbene tungsten complex can react with the Witting reagent to form alkoxy-substituted olefins. In this paper, the carbene tungsten complex was further used to react with dichloromethyl Wittig reagent to synthesize 1,1-dichloro-2-alkyloxy alkene. It is well-known that 1,1-dihaloolefins are a class of precursor compounds that produce unsaturated carbenes. Therefore, through the reaction between carbene tungsten complex and dichloro-Wittig reagent, we can further study the properties of alkoxy-substituted unsaturated carbene.
