The term chiral poisoning as a deactivating strategy has been proposed for the asymmetric hydrogenation reaction of dimethyl itaconate catalyzed by CHIRAPHOS-Rh complex (Scheme 8.5). The combination of racemic CHIRAPHOS-Rh complex and (5)-METHOPHOS 6 as a catalyst poison yields the hydrogenated product in 49% ee. (5)-METHOPHOS is believed to bind to the (S. S -CHlRAPHOS-Rh complex preferentially, as the use of enantiopure (R,R)-CHlRAPHOS-Rh complex affords the product with 98% ee. 

Different strategies have evolved for thermochemical hydrogen production to effectively utilize the potentials of, in particular, nuclear and solar thermal energy sources. These strategies, which we discuss below, can be categorized depending upon the number of process steps involved and whether electrolysis is employed in a reaction.
