(Im)P-P(Dipp)˙ (1˙), a rare example of a neutral, mixed substituted diphosphene radical, has been prepared by reduction of (Im)PP(Dipp)[OTf] (2[OTf]) and (Im)PP(Cl)(Dipp) (3) with cobaltocene (CoCp) (Im = 4,5-dichloro-1,3-bis(1,3-diisopropylphenyl)-imidazol-2-yl, Dipp = 2,6-diisopropylphenyl). Radical compound 1˙ readily activates white phosphorus (P), resulting in the formation of an intriguing octaphosphane butterfly compound P(Im)(Dipp) (4).
(Im)P-P(Dipp)˙ (1˙)是一种罕见的中性、混合取代二膦烯自由基，它是通过用二茂钴（CoCp）还原(Im)PP(Dipp)[OTf] (2[OTf])和(Im)PP(Cl)(Dipp) (3)制备得到的（Im = 4,5-二氯-1,3-双（1,3-二异丙基苯基）-咪唑-2-基，Dipp = 2,6-二异丙基苯基）。自由基化合物1˙能轻易活化白磷（P），从而形成一种有趣的八磷烷蝴蝶化合物P(Im)(Dipp) (4)。
