A novel synthesis of the pyrazole ring involving SO2 extrusion by flow vacuum pyrolysis in the 1,2,6-thiadiazine 1,1-dioxide system is described. The reaction has potential industrial significance for routes to pyrazoles or functionalized pyrazoles that do not involve hydrazines.
描述了在 1,2,6-噻二嗪 1,1-二氧化物系统中通过流动真空热解 SO2 挤出的吡唑环的新合成。该反应对于不涉及肼的吡唑或官能化吡唑的路线具有潜在的工业意义。
