The synthesis and catalytic activity of nickel metallodendrimers (C1-C6) are reported. The metallodendrimers were synthesized by the coordination of the metal precursors, Ni(OAc)2 and Ni(DME)Br2, to the periphery of salicylaldimine and iminopyridyl modified dendritic ligands, DL1-DL6, based on the generation 1 to generation 3 diaminobutane polypropylene imine (DAB-PPI) dendrimers. The metallodendrimers were tested in the oligomerization of ethylene and were found to be active catalysts. When using this catalyst system, it was found that a tandem process occurred in which ethylene oligomerization was followed by Friedel-Crafts alkylation of the reaction solvent, toluene. The latter process is mediated by the aluminium co-catalyst, EtAlCl2.

Copper-catalyzed cross-coupling reaction of organoboron compounds with primary alkyl halides and pseudohalides

Non-activated alkyl electrophiles, including alkyl iodides, bromides, tosylates, mesylates, and even chlorides, underwent copper-catalyzed cross-coupling with aryl boron compounds and alkyl 9-BBN reagents (see scheme; 9-BBN=9-borabicyclo[3.3.1]nonane). The reactions proceed with practically useful reactivities and thus complement palladium- and nickel-catalyzed Suzuki-Miyaura coupling reactions of alkyl halides.
