Hydroamination and hydrothiolation are the most efficient and completely atom-economical process to construct important enamine and vinyl sulfide intermediates in pharmaceutical and organic chemistry. The cyclic trimeric phosphazene base (CTPB) showed gre

Highly effective coupling of imidazoles with (E)-vinyl halides can be achieved by using readily available iron catalysts under ligand-free, copper-free and palladium-free conditions. Coupling of (E)-vinyl bromides led to (Z)-products predominantly, while
Cu2O-catalyzed Ullmann-type reaction of vinyl bromides with imidazole and benzimidazole

Cu2O was found to be an efficient and economical metal catalyst in the Ullmann cross-coupling reaction of vinyl bromides with imidazole or benzimidazole. The system Cu2O/ethyl 2-oxocyclohexanecarboxylate showed high catalytic activity in MeCN at 80-90 °C. The reaction gave the corresponding coupling products in good to excellent yields.
