The Synthesis of Dipyrazolylmethanes, X-Ray Structure Analysis
摘要:
A small dipyrazoylmethane compounds library was established via the reaction of 5-alkyl- and 5-aryl-2-aryl-3H-pyrazol-3-ones with DMSO in the presence of NaOAc center dot 3H(2)O as base using LiBr center dot H2O as additive at 100 degrees C.
