Title
(EN) NOVEL HIGH YIELDING, ECONOMICAL, ECO-FRIENDLY AND SELECTIVE METHOD FOR THE PREPARATION OF DEUTERATED ALKYL ARENES.
Abstract
(EN)
Present invention relates to a novel high yielding, economical, eco-Friendly and selective method for the preparation of stable deuterated alkyl arenes. In this invention, an efficient method for the site-selective deuteration of alkyl arenes under super basic conditions has been developed. A robust reaction condition for the deuteration of toluene, xylene and mesitylene has been investigated.In contrast to other organic solvents, DMSO-d6 is inflammable, and environment friendly which remarkably effects the rate and selectivity of organic reactions. The step economic deuteration in basic medium proceeded with high functional group tolerance. A straightforward route for a high level of deuterium incorporation and low cost of the reagent make this a useful method for isotopic labeling studies. The deuterated alkyl arenes have various industrial applications as they are used as starting substrates for many organic reactions, viz., in kinetic isotopic labelling studies, mechanistic pathways of the reaction and as NMR solvents. The developed method for synthesis of deuterated alkyl arenes reduces the production cost by 10 to 15 fold and results into a stable product which does not need any stabilising agent.
