资源简介：
Rhodium-catalyzed
addition–cyclization of hydrazines with
alkynes has been achieved to afford highly substituted pyrazoles under
mild conditions. The cascade reaction involves two transformations:
addition of the C–N bond of hydrazines to alkynes via unexpected
C–N bond cleavage and intramolecular dehydration cyclization.
