摘要：

Two [3+1] fragmentations of the Lewis acid stabilized bicyclo[1.1.0] tetraphosphabutanide Li[Mes*P-4 center dot BPh3] (Mes*=2,4,6-tBu(3)C(6)H(2)) are reported. The reactions proceed by extrusion of a P-1 fragment, induced by either an imidazolium salt or phenylisocyanate, with release of the transient triphosphirene Mes*P-3, which was isolated as a dimer and trapped by 1,3-cyclohexadiene as a Diels-Alder adduct. DFT quantum chemical computations were used to delineate the reaction mechanisms. These unprecedented pathways grant access to both P-1- and P-3-containing organophosphorus compounds in two simple steps from white phosphorus.
