The thermal decomposition of n-alkyltriarylphosphonium alkoxides
Abstract
Tri-p-deuteriophenylpropylphosphonium bromide and sodium methoxide at 260° give p-deuterioanisole free from other isomers and di-p-deuteriophenylpropylphosphine. Similarly, tri-m-chlorophenylpropylphosphonium bromide gives pure m-chloroanisole.
