摘要

The synthesis of a new series of bolaform-and gemini-type phosphorus acid surfactants is described. The Pudovik addition reaction of P–H bond tetraoxyspirophosphoranes to symmetrical, prochiral bis-imines bearing different more or less long and rigid linkers occurs instantaneously at room temperature. This reaction is diastereoselective and quantitatively leads to the corresponding alkyl-bis-[α-aminospirophosphoranes] in good to high ...
