Abstract: Herein, we report the synthesis of various heterocyclic ring systems containing 1,2,3‐triazole from the reactions of acid hydrazides and commercially available reagents, using efficient and simple procedures. Reactions of certain 1,2,3‐triazole‐4‐carbohydrazides and α‐bromoketones in boiling… read more here.

Abstract: A direct introduction of vinyl ethers into C–H bond of heterocycles is reported. For this purpose, decarboxylative direct C–H cross-coupling of 1,3-diazoles with α-carboxyvinyl ethers as coupling partners was achieved under Pd(0)/Cu(I) cooperative catalysis to… read more here.
