Braslau, Rebecca,Anderson, Marc O.
, p. 4227 - 4230 (1998)
Aryl radicals are generated by oxidation of aryl hydrazine with PbO2 or via photolysis of aryl iodide. Abstraction of deuterium from dideuteroglycine derivatives is demonstrated as a model for the possible reaction of 1,4-aryl diradicals with a

Contrary to conventional deuteration approaches which typically entail deuterated solvents and/or moisture exclusion, an unprecedented deutero-deiodination reaction attainable in aqueous (H2O) solution is presented herein. By utilizing the stability of inorganic deuterated calcium/sodium hypophosphites against wayward H/D isotopic exchange within pH 2.5-11.7, these shelf-stable, nontoxic, cost-effective, and environmentally benign deuteration reagents mediate deuteration of a broad range alkyl and aryl iodides with ample isotopic incorporation in aqueous (H2O) solution.

supporting information, p. 6323 - 6327 (2020/11/09)
Herein, novel photoinduced catalyst-free deborylation-deuteration of arylboronic acids with D2O is reported. The protocol was compatible with a variety of functionalities, including halogen, alkoxy, cyano, sulfonyl, trimethylsilyl, trifluoromethoxy, alkyl, hydroxyl, free acid, amide, and heteroaromatic rings. A wide range of deuterated products were obtained in good yields with a high level of deuteration. This method provides a green and practical pathway to synthesize deuterium labelled compounds under mild conditions.

A convenient method for palladium-catalyzed reductive deuteration of organic substrates using deuterated hypophosphite in D2O
Oba, Makoto
, p. 215 - 219 (2015/05/20)
A convenient method for the deuteration of organic substrates using deuterated hypophosphite as the deuterium source was investigated. Transfer deuteration of organic substrates, such as aromatic halides, alkenes, alkynes, epoxides, and O-benzyl derivativ
Two-chamber hydrogen generation and application: Access to pressurized deuterium gas
Modvig, Amalie,Andersen, Thomas L.,Taaning, Rolf H.,Lindhardt, Anders T.,Skrydstrup, Troels
, p. 5861 - 5868 (2014/07/08)
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 H2 and DCl in deuterated water for D2. 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.
CAN-mediated oxidation of electron-deficient aryl and heteroaryl hydrazines and hydrazides
?tefane, Bogdan,Polanc, Slovenko
scheme or table, p. 1279 - 1282 (2009/04/06)
Aryl and heteroaryl hydrazines and hydrazides were successfully oxidised using CAN, deriving dehydrazinated products. The reaction pathway strongly depends on the nature of the substrate, resulting in the formation of hydrocarbons or alkoxy derivatives. When deuterated solvents such as methanol-d4 or acetonitrile-d3 were used, a regiospecific incorporation of deuterium was achieved. Georg Thieme Verlag Stuttgart.
