Reactions of 2-(4,5-dihydro-3-furyl)-1,3-diphenyl-1,3-diaza-2λ3-phospholidine (1) with nitrile imines are multistep processes involving cleavage of one P-N bond of the diazaphospholidine ring to form substituted 5-(2-chloroethyl)-4-(N,N′-diphenylethylenediamino)-1,4-dihydro-1,2,4λ5-diazaphosphorines 4 as final products. Analogs of phospholidine 1, namely, 4,5-dihydro-3-furylphosphonous dipiperidide and dimorpholide, react with C,N-diphenylnitrile imine with retention of both P-N bonds to give 5-(2-hydroxyethyl)-1,2,4-diazaphosphorinium chlorides.
2-(4,5-二氢-3-呋喃基)-1,3-二苯基-1,3-二氮-2λ3-磷环(1)与腈亚胺的反应是多步过程,涉及断裂一个二氮磷环的P-N键,最终生成取代的5-(2-氯乙基)-4-(N,N′-二苯基乙烯二胺)-1,4-二氢-1,2,4λ5-二氮磷烯(4)。磷环的类似物,即4,5-二氢-3-呋喃基磷酸二哌啶酰和二莫尔酰,与C,N-二苯基腈亚胺反应时保留了两个P-N键,生成5-(2-羟乙基)-1,2,4-二氮磷鎓氯化物。
