Pt(hfac)(2) [hfac = 1,1,1,5,5,5-hexafluoro-2,4-pentanedionato] reacts with ethylene when irradiated at 350 nm to yield a single photoproduct which we have isolated for the first time. X-ray diffraction reveals this to be Pt(hfac)(2)(eta(2)-C(2)H(4)), a five coordinated complex, with two bidentate...
