PHOSPHORYLATED N-PROPARGYLAMINES-SYNTHESIS AND REACTIONS
摘要:
Reaction of N-propargylaminophosphites with methyl iodide or sulfuryl chloride leads to N-propargylaminophosphonates or N-propargylaminophosphates. In the interaction of N-propargylaminophosphites with methyl iodide in the presence of triethylamine hydrochloride three reactivities were noted: 1) cyclization affording azaphospholes; 2) Arbuzov-type reaction giving N-propargylaminophosphonates and 3) addition of HCl to the triple bond leading to N-allylaminophosphonates. Treatment of N-propargylaminophosphonates and -thiophosphates with HCl (gas) leads to phosphorylated N-propargylammonium salts, not to the formation of adducts.
