Photolysis of diethylthallium bromide in cyclohexane is a radical process involving cleavage of the thallium-carbon bond, which yields ethylcyclohexane and dicyclohexyl, as well as other products. Photoelectron transfer from benzyltributylstannanes to 10-methylacridinium ion results in cleavage of the metal-carbon bond, to give the corresponding benzyl radicals, rather than benzyl cations. Photochemical homolysis of Re- and Ru-alkyl bonds in Re(alkyl)-(CO)3(diimine) and Ru(I)(alkyl)(CO)2(diimine) complexes has been studied by Fourier transform ESR. In related manganese complexes, Mn(R)(CO)3(di-imine), elimination of CO is the predominant pathway when R = methyl, but Mn-alkyl homolysis occurs when R = benzyl. 

Champness and coworkers prepared the complexes c-[M(bpydc)(CO)3X] (M = Mn, Re bpydc = 2,2 -bipyridine-5,5 -dicarboxylate) and reacted them with manganese(II) to form MOFs in which Mn(II) cations are the nodes and the diimine complexes are the linkers. On treatment with UV radiation, fac to mer isomerization was observed, as witnessed by IR spectroscopy and X-ray crystallography. ... 

Several catalysts that can effect enantioselective epoxidation of unfunctionalized alkenes have been developed, most notably manganese complexes of diimines derived from salicylaldehyde and chiral diamines (salens).62...
