Sonochemistry in the diphosphirane series

Sonication improves substantially the rate of formation of diphosphene 1 with respect to standard procedures. The cyclopropanation of 1 using sonochemical generation of methylene or halogeno-carbenes constitutes an interesting alternative in the diphosphi

A CONVENIENT NEW ROUTE FROM DIPHOSPHENE TO 1,3-DIPHOSPHA-ALLENE AND DYNAMIC NMR STUDIES OFF THE 2,4,6-TRI-t-BUTYLPHENYL DERIVATIVE

Addition of dihalocarbenes to a diphosphene gave diphosphiranes which undergo rearrangement on treatment with alkyllithium reagents to afford 1,3-diphospha-allene; dynamic NMR studies on the allene are described.
