N-heterocyclic carbene induced reductive coupling of phosphorus tribromide. Isolation of a bromine bridged P-P bond and its subsequent reactivity
The room temperature reaction of a 1 : 1 mixture of phosphorus tribromide (PBr3) and the N-heterocyclic carbene 1,3-bis(2,6-diisopropylphenyl)-imidazol-2-ylidene (IPr) quantitatively affords the Lewis acid-base adduct (IPr)PBr3 (1). Interestingly, when 1 is heated between 55 and 65 °C for a period o...
