One-Pot Dual Substitutions of Bromobenzyl Chloride, 2-Chloromethyl-6-halogenoimidazo[1,2-<i>a</i>]pyridine and -[1,2-<i>b</i>]pyridazine by Suzuki-Miyaura Cross-Coupling Reactions
very simple, mild and inexpensive palladium-catalyzed cross-coupling of (hetero)arylboronic acids with benzylic halides occurs in good yield. This method was successfully expanded to two heterocyclic electrophiles and allowed one-potdualsubstitutions of bromobenzylchloride, 2-chloromethyl-6-halogenoimidazo[1,2-a]pyridine or -[1,2-b]pyridazine, leading to numerous new unsymmetrical methylene-linked
