The compounds (η²-diarsane)bis(phenyl)platinum(II) with either a CH3, (CH3)2CH, (CH3)3C, F, Br, CF3, (CH3)3Si in the 4-position of the platinum-bound phenyl rings have been synthesized and studied photochemically.After excitation into the longest wavelength absorption band they eliminate the two substituted, platinum-bound rings as a biphenyl, but are photo-stable when excited by shorter wavelength UV-radiation.The elimination is exclusively intramolecular and stereospecific; it is an example of a concerted pericyclic at a transition metal.
