Abstract

Abstract Bifunctional aminophosphanes (Et2N) 2P-[CH2] n,-P (NEt2) 2 (n= 1–10)(1) and Et2NP (R)-[CH2] nP (R) NEt2 (n= 2–4, R= Alkyl, Ph)(2), which are valuable intermediates in organophosphorus synthesis, are obtained by two methods. Because of the marked nucleophility of phosphorus in 1 and 2, reactions with Lewis acids take place very smoothly as is shown by preparation of (Et2N) 2P (X)-[CH2] 4-(X) P (NEt2) 2 (X= O, S, Se, Te, BH3, ...
