This article discusses the full details of optimization studies of the phosphine-catalyzed ketene homodimerization reaction and the development of an asymmetric variant. It also reveals studies towards the development of a phosphine-catalyzed ketene heterodimerization reaction, and includes a discussion of possible reaction mechanisms supported by spectroscopic analysis of intermediates and trapping experiments.
Full details of optimisation studies of the phosphine-catalyzed ketene homodimerization reaction and the detailed development of an asymmetric variant are discussed. Studies towards the development of a phosphine-catalyzed ketene heterodimerization reaction are revealed. A discussion of possible reaction mechanisms for the dimerization reactions, supported by spectroscopic analysis of intermediates and trapping experiments, is also presented. (C) 2020 The Author(s).
