Synthesis and Rearrangement of Intramolecularly Stabilized 1.sigma.2,3.sigma.2-Diphosphaallylic Cations into Intramolecularly Stabilized 1.sigma.1,3.sigma.3-Diphosphaallylic Cations
Résumé
Two equivalents of boron trifluoride-diethyl ether complex or 1 equiv of trifluoromethanesulfonic acid reacts with C-[bis(diisopropylamino)phosphino]-C,P-bis(diisopropylamino)phosphaalkene 1, cleaving one of the diisopropylamino substituents at the
