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 PhCCPh 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.

reacts thermally with PhCCH to produce CPh)2(dppe)>, which has been prepared by alternative routes.Similar treatment of initially produces CPh)2(dpmm)>, which rearranges to give cis,cis-CPh)4(μ-dppm)2>.Reaction of with PhCCH/KOH/18-crown-6, or with (PhCC)SnMe3, gives CPh)2(dpmm)>, which may be converted to the cis,cis-dimer by addition of oxalic acid.Ultraviolet irradiation or refluxing with a trace amount of dppm converts CPh)2(dppm)> to trans,trans-CPh)4(μ-dppm)2>, but the cis,cis-dimer is stable under these conditions. (L = PPh3, PEt3) complexes also react thermally with PhCCH to yield CPh)2L2> species.
