The behaviour of quaternary salts under reduced pressure. Part II. Decomposition of the N-methylammonium hydroxides of benzyl-, dibenzyl-, and diphenylmethyl-amines

Abstract

The pressure dependence of Sommelet–Hauser and concurrent Stevens' rearrangements of some onium salts has been investigated. The ionic reaction has been shown to be very susceptible to reduced pressure, whereas competing radical reactions are relatively unaffected. The reasons for the enhanced rate of Sommelet–Hauser rearrangements at low pressures are discussed.
