1-苯基-1,5-二氢-4H-咪唑-4-酮 | 1-phenyl-1H-pyrazol-3-ol | 1008-79-3 | C9H8N2O | 160.175 |
The mechanism of a DMF-catalysed electrophilic/nucleophilic chlorination of pyrazole is illustrated with the aid of calculations of the natural bonding orbital charges. Its high regioselectivity and good functionality tolerance of nine pyrazole substrates have been experimentally demonstrated.
