Dismembering molecules: The stable boryl(phosphino)carbene 1 can cleave small organic dioxide molecules. With CO2 and SO2, 1 gives, respectively, the phosphacumulene ylide [Mes(iPr2N)B-O-P(CCO)(NiPr2)Mes] (see scheme and structure) and boryl(phosphoryl)sulfine [Mes(iPr2N)B-C(SO)-P(O)(NiPr2)Mes] which have been structurally and spectroscopically characterized.
