A robust magnetic nanoparticle-supported N-heterocyclic carbene-palladacycle has been readily synthesized by directly anchoring the structural defined acenaphthoimidazolylidene palladacycle with a long tail on magnetic nanoparticles (MNPs), and functioned as a solid molecular catalyst and exhibited extremely high catalytic activity towards the challenging Suzuki-Miyaura cross-coupling reactions between less-studied heterocyclic 9-chloroacridine and diverse boronic acids. Remarkably, the catalyst could be used 5 times without obvious loss of activity highlighting the efficiency of our strategy of immobilization of previledged catalysts.

(Chemical Equation Presented) Aryl mesylates are found to be applicable as electrophiles in organosilicon-mediated coupling reactions. The catalyst system comprising 2 mol % of Pd(OAc)2 and CM-phos supporting ligand is highly effective in catalyzing Hiyama cross-coupling of various aryl and heteroaryl mesylates. Interesting acid additive effects show that the presence of 0.25-0.50 equiv of acetic acid efficiently suppresses the mesylate decomposition and generally promotes the coupling product yields.

Methods are proposed for preparation of 5- and 6-substituted 2-methylbenzothiazoles by reactions of organozinc and organotin compounds with 5- and 6-bromo-2-methylbenzothiazoles, catalyzed by palladium complexes. The reactions of organozinc compounds with 5(6)-bromo-2-methylbenzothiazoles occur in THF at 20°C in the presence of PdCl2(dppf), and those of organotin compounds are carried out in DMF, aqueous DMF, or water at 40-100°C in the presence of PdCl2, Pd(OAc)2, or PdCl2(PPh3)2.
