摘要：

A novel and efficient protocol for the construction of substituted pyrazoles from benzenesulfonohydrazides and pentane-2,4-diones under catalyst-free conditions was developed. This protocol features excellent tolerance to a variety of functional groups, step economy, simple operation with inexpensive reagents, mild reaction conditions, and can be scaled-up.
