Solvolysis Reactions of tert-Butyl Chloride and Methyl Tosylate in Trimethoxyborane Methanol Mixtures

The solvolysis rates of t-butyl chloride and methyl tosyla.te were measured in various trimethoxyborane - methanol mixtures. The ionizing power and the nucleophilicity for the respective solvent mJxtures were determirrled, and the suitability of this new solvent system for the study of solvolytic reactions is discussed. At elevated temperatures a reaction of hydrogen chloride, liberated in the solvolysis of t~butyl chloride, with the solvent was observed, and the r esults seem to indicate that methyl chloride is the reaction product
