aryl-alkyl alkenes, the amidation selectively takes place at the alkyl-substituted allylic carbon. Meanwhile, the better selectivity was also observed in the unsymmetrical aryl-aryl alkenes having an electron-withdrawing substituent at one of the aryl groups. A possible reaction mechanism involving a π-allyl iridium intermediate was proposed and supported by the deuterium labeling studies. The deuterium labeling
Towards efficient conversion of allylalcohol into value‐added compounds: The first examples of zeolite‐catalyzed substitution of the hydroxy group in allylalcohols with nucleophiles were developed. The zeolite‐catalyzed substitution reaction is broadly adaptable to substrates under relatively mild reaction conditions.
