On Derivatisation Reactions of 2-Chloro-3-Dichlorophosphanyl-1-Methyl-1.3.2-Diazaphosphorinane

Abstract

Derivatisation reactions of 2-chloro-3-dichlorophosphanyl-1-methyl-1.3.2-diazaphosphorinane 1 with protic nucleophiles like HNEt₂, CH₃OH, C₂H₅OH and the Franz-reagent NEt₃3HF forming the substituted N-phosphanyldiazaphosphorinanes 2-12 are described. The preferential nucleophilic attack on the exocyclic phosphanyl group of 1 in partial replacement reactions is discussed by means of ³¹P-, ¹H- and ¹³C-NMR data.
