## Abstract Selective incorporation of deuterium by platinum‐catalyzed exchange for six ribonucleosides and two 2′‐deoxyribonucleosides has been studied as a function of catalyst/substrate ratio, temperature, time and concentration. In addition to exchange of carbon‐bound hydrogens in purines, pyri
The rate of CHI disappearance in a shock-heated CHI: Dz: Ar = 9.70: 9.86: 80.44 mixture was monitored by coincidence absorption of the 2948 cm-I He-Ne laser line over the shockfront temperature range of 1900-2300K. Comparison with CHr pyrolysis results by means of computer simulations suggested that
## Abstract Conventional thermal and microwave conditions were compared for hydrogen–deuterium (H/D) exchange reactions of aminobenzoic acids catalysed by NaBD~4~‐activated Pd/C or RhCl~3~ with D~2~O as the deuterium source. We also investigated different NaBD~4~‐activated metal catalysts (includin
## Abstract Preparation of deuterium‐labeled rutin by hydrogen exchange reaction under alkaline condition is described. Hydrogens at positions 2′, 5′ and 6′ of rutin were replaced with deuteriums only on heating, while hydrogens at positions 6 and 8 were readily replaced at room temperature. On the
