More recently, reductive elimination of aryl ethers has been reported from complexes that lack the activating substituent on the palladium-bound aryl group (Equation (55)). These complexes contain sterically hindered phosphine ligands, and these results demonstrate how steric effects of the dative ligand can overcome the electronic constraints of the reaction.112,113 Reductive elimination of oxygen heterocycles upon oxidation of nickel oxametallacycles has also been reported, but yields of the organic product were lower than they were for oxidatively induced reductive eliminations of alkylamines from nickel(II) mentioned above 215-217... 

In a related reaction, photolysis of the 18-electron complexes fy -CpMo(dmpe)2H3 and (t -j-PrCp)MoL2H3 (L2 = two P-donor ligands or one chelating diphosphine) induces reductive elimination of H2 to produce the monohydrido complexes . These 16-electron complexes can oxidatively add aryl C-H bonds and catalyze H-D exchange in the aryl ring.
