Reaction of tervalent phosphorus compounds with sterically hindered N-halogenoamines (1,2) proceeds via the formation of halogenophosphonium intermediates (3), containing an anion R2N-.Intermediates react with alcohols to afford alkoxyphosphonium salts (6), transform into halogenophosphonium salts (4) or P-halogenoylids.Sterical hindrances at the nitrogen atom of intermediates (3) favour the formation of P-halogenoylids.The P-chloroylid (10) exists in the chlorotropic equilibrium with the α-chloroalkylphosphine (16). Key words: Sterical hindered N-halogenoamines, N-chlorodiisopropylamine, N-chloro-trimethylsilyl-tert-butylamine, alkoxyphosphonium salts, P-chloroylids, 1,2-CP-chlorotropy, positive halogen, NMR spectra, halogenophilic substitution.
