Article abstract of DOI:10.1016/S0040-4020(98)00798-4

Microwave irradiation induces the thermal isomerization of pyrazolyl hydrazones to the corresponding azomethine imines which undergo 1,3-dipolar cycloaddition with electron-poor dipolarophiles in a few min with good yields. By classical heating, several d
