Two-Chamber Hydrogen Generation and Application: Access to Pressurized Deuterium Gas
2014-06-20T00:00:00Z (GMT) by
Hydrogen and deuterium gas were produced and directly applied in a two-chamber system. These gaseous reagents were generated by the simple reaction of metallic zinc with HCl in water for H<sub>2</sub> and DCl in deuterated water for D<sub>2</sub>. The setup proved efficient in classical Pd-catalyzed reductions of ketones, alkynes, alkenes, etc. in near-quantitative yields. The method was extended to the synthesis and isotope labeling of quinoline and 1,2,3,4-tetrahydroquinoline derivatives. Finally, CX-546 and Olaparib underwent efficient Ir-catalyzed hydrogen isotope exchange reactions.
