摘要

Exclusive formation of either 2-or 4-trifluoromethyl (1H, 5) arylodiazepines (5, 7)(6, 8) was observed in the condensation of 1, 1, 1-trifluoro-3-(isobutoxymethylene)-2-propanones 2 3 with o-arylenediamines 4 under microwave irradiation conditions. Thermal reactions under the same temperature and time produced no products. Orthoaminophenols 9 and o- aminothiophenol 12 with 2 and 3 under the same conditions produced the respective ...
