An efficient method for the synthesis of alkyl indium reagents via an indium(iii) or lead(ii) halide-catalyzed direct insertion of indium into alkyl iodides is developed. NMR and ESI-MS analyses indicated the formation of a mixture of an alkyl indium dihalide (RInX2) and a dialkyl indium halide (R2InX).
An efficient method to produce diarylpyrazolo[3,4-b]pyridines derivatives via combination of chemoselective Suzuki–Miyaura cross-coupling reactions has been developed.
We have described an efficient method for oxidative cross coupling reactions between activated N–H amines and terminal alkynes using heterogeneous Cu2(BDC)2(BPY) as recyclable catalyst (BDC = benzene-1,4-dicarboxylate; BPY = 4,4′-bipyridine).
