Abstract

Abstract Tri-tert-butyl-cyclotriphosphane is obtained by the dehalogenation of 1,3-diiodo-1,2,3-tri-tert-butyl-triphosphane with lithiumhydride. This reaction represents a so far unknown type of ring-closure leading to cyclotriphosphanes, which corresponds to the classical synthesis of cyclopropanes starting from 1,3-dichloropropanes.
