A unique and valuable method has been developed for the hydrogenation of aromatic and aliphatic alkenes. The catalytic InBr3, 1,3-benzodioxole, and residual H2O in the reaction mixture are utilized as a practical source of deuterium incorporation. Experimental studies demonstrate that the transfer of hydride from 1,3-benzodioxole to carbocationic intermediate remains the critical step.
A unique and valuable methodology is developed for the hydrogenation of aromatic as well as aliphatic 1,1 -di-and trisubstituted alkenes. In the presence of catalytic InBr3, readily available 1,3-benzodioxole and residual H2O present in the reaction mixture are utilized as a hydrogen gas surrogate and proved to be a practical source of deuterium incorporation into the olefins on either side by varying the source of the starting deuterated 1,3-benzodioxole or D2O. Experimental studies show the transfer of hydride from 1,3-benzodioxole to the carbocationic intermediate generated from the protonation of alkenes by the H2O-InBr3 adduct remains the critical step.
