Further syntheses of quinquevalent spirophosphoranes by using N-chlorodi-isopropylamine
Abstract
Spirophosphoranes have been obtained from cyclic tervalent phosphorus compounds and 1,2-difunctional com-compounds HX(C)2YH (X, Y = O, NR, or S), benzohydroxamic acid, benzohydrazide, or benzamidoxime in the presence of N-chlorodi-isopropylamine.
