The Effect of Light Photochemically Induced Reductive Elimination

The Effect of Light Photochemically Induced Reductive Elimination 

Most reductive elimination reactions are induced thermally, but some important reductive elimination reactions are induced photochemically. Most examples of such reductive eliminations form dihydrogen from metal-dihydride complexes. Two examples of the photochemical reductive elimination of dihydrogen to generate intermediates that add alkanes are shown in Equations 8.6 and 8.7. In these examples, the photochemical irradiation provides the energy to induce the reductive elimination process. 

Photochemically induced reductive elimination can also result from initial photochemical extrusion of a dative ligand. For example, irradiation of [lrH,Cl(CO)(PPhj)J leads to
