摘要
2,3-Di-tert-butyl-1-telluradiphosphirane was isolated in pure state by trap to trap condensation after reaction of 1,2-Di-tert-butyl-1,2-dichlorodiphosphane with sodium telluride in pentane suspension. The telluradiphosphirane and other P-Te heterocycles (t-BuP)(n)Te(m) (n = 2, m = 1; n = 3, m = 1,2; n = 4, m = 1,2) are formed from 1,2-Di-tert-butyl-1,2-dichlorodiphosphane or tert-butyldichlorophosphane with bis(trimethylsilyl)telluride and from the reaction of tert-butylbis(trimethylsilyl)phosphane with elemental tellurium. The proposed structures of the P-Te heterocycles are based on P-31- and Te-125-n.m.r. and MS data
