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 (CH(3))(2)S gives rise to an unusual N,N'-bis(ethyl)sulfurousdiamide ligand in an apparently unprecedented process involving C-C bond formation.
