Introduction	The photolysis of a platinum(II) azide complex in the presence of styrenes leads to C=C double bond cleavage through dissociative olefin imination, forming aldimido (Pt II–N=CHPh) and formimido (Pt II–N=CH2) complexes as main products. Spectroscopic and quantum chemical analyses indicate a mechanism starting with the decay of the metallonitrene photoproduct (Pt II–N) via bimolecular coupling and nitrogen (N2) loss. The subsequent platinum(I) complex triggers a radical chain mechanism through a dinuclear radical-bridged species (Pt II–CH2CHPhN •–Pt II) as a precursor to C–C scission. The preference for the Pt I mediated route over styrene aziridination is due to the unique nucleophilicity of the triplet metallonitrene.
