A new efficient synthesis of pyrazoles from hydrazonoyl halides and β-oxophosphonates

A new practical and efficient synthesis of 1,3,5-trisubstituted pyrazoles has been developed by reacting of hydrazonoyl halides with β- oxophosphonates under mild conditions in good yields with excellent regioselectivity. This process employs an addition-elimination sequence. Wide scope, functional group compatibility has been established.

α,β-UNSATURATED THIOLATES AND THEIR ANALOGS IN CYCLOADDITION REACTIONS. XVIII. REACTION OF 2-PHENYLETHYNYLTELLUROLATES WITH C-ETHOXYCARBONYL-N-PHENYLNITRILIMINE

The reaction of sodium or lithium 2-phenylethynyltellurolates with C-ethoxycarbonyl-N-phenylnitrilimine leads to the oxidation product of ethynyltellurolate - di(2-phenylethynyl)telluride, a product of reduction of the initial nitrilimine - the phenylhydr
