This paper describes the synthesis of carbon functional groups organic silicon compound with phase transfer catalysis. We have found the traditional phase transfer catalyst's efficiency is not satisfying in this system. According to the theory that compound with similar configuration and composing can dissolve each other and the catalyst with organic silicon group should benefit for catalyst's transferring and exchanging in this system. Basing on traditional catalyst of quaternary ammonium salt, we synthesize the novel phase transfer catalyst containing N-Si bonds, which can synthesize acyloxyalkyl silicon compound with more productivity in a mild condition.We have synthesized a series of phase transfer catalysts containing organic silicon compound, which including the quaternary ammonium salt with N-Si bonds and also including the complex compounds with N-Si match bonds. There is a great disputed between investigators for the latter's configuration and existing state. We have investigated its preparation method and catalyze performance, and also have launched great energy into describing its configuration.with IR, NMR and EA,The catalytic capability of the catalyst was validated in the esterification reaction of chlorine substituted Hexamethyl disiloxane, chlorine substituted octamethyl cyclotetra siloxane with potassium acetate. To begin with, we have chloridized the two compounds with the method that literature provided. One is chloridized with chlorine, and the other is chloridized with sulfuryl chloride. Two methods all can reach the aim, we get a mixture that include one chlorine substituted production and multi chlorine substituted production. we separated them though rectified the mixture in vcuum conditions.
