Irradiation at 254 nm of CH3CN/C6H6 or PhCn solutions of produces 2 equiv. of CO2, and in the presence of PhCl or PhI yields .With CO or PhC<*>CPh the products are or CPh)(dppe)>, but in the latter case extended photolysis yields CPh)(dppe)>.Photolysis in the presence of H2 gives a mixture of the ⁺ and ⁺ cations.Simple elimination of CO2 does not occur in all cases, as illustrated by the formation of when is photolyzed in the presence of methanol.Photochemical reactions of the related complexes (L2 = dppm, dcpe) are also described.
