Mizoroki–Heck coupling reactions of arenediazonium tetrafluoroborate salts catalyzed by aluminium hydroxide-supported palladium nanoparticles
摘要:
Mizoroki-Heck cross-couplings of arenediazonium tetrafluoroborate salts catalyzed by highly active aluminium hydroxide-supported palladium nanoparticles catalyst have been investigated for the first time. The reactions are performed at 25 degrees C in EtOH without any base and ligand to afford the corresponding coupling products in good to excellent yields under non-anhydrous and non-degassed conditions.

Arenes and electron‐deficient olefins can be oxidatively coupled through a biomimetic Pd(OAc)2‐catalyzed transformation. CH activation of the arene partner is effected under reaction conditions of low catalyst loading, normal oxygen pressure, and using p‐benzoquinone and iron phthalocyanine as electron‐transfer mediators (ETMs). By controlling catalyst loading, the reaction can be made selective for

An efficient PdCl2-Dppc+-PF6–-[bmim][PF6] catalytic system has been developed for the Heck coupling reaction of various aryl iodides with olefins. The catalytic system allows the coupling reaction to proceed smoothly in excellent yields and can be recycled 5 times with minimal loss of activity.
