Unprecedented carbon-carbon bond formation induced by photoactivation of a platinum(IV)-diazido complex

UVA-induced photodecomposition of a Pt-IV-diazido complex involves not only reduction to Pt-II and N-2 release, but also O-2 evolution and formation of nitrene intermediates, whose trapping with (CH3)(2)S gives rise to an unusual N,N'-bis(ethyl)-sulfurousdiamide ligand in an apparently unprecedented process involving C-C bond formation.
