One pot synthesis of 5-per(poly)fluoroalkyl-2,3-dihydro-1,4-diazepines
A series of 5-per(poly)fluoroalkyl-2,3-dihydro-1,4-diazepines have been synthesized from reaction of RfCF2I with vinyl ethyl ether and ethylenediamine. A possible reaction pathway is suggested.
Fluoro organics: A facile and exclusive synthesis of novel 2- or 4-trifluoromethyl(1H,5)arylodiazepines
Exclusive formation of either 2- or 4-trifluoromethyl(1H,5)arylodiazepines 4/3 was observed in the condensation of 1,1,1-trifluoro-3-(isobutoxymethylene)-2-propanones (R = H,COCF3) 2 with o-arylenediamines 1 under microwave irradiation conditio
Synthesis of 5-per(poly)fluoroalkyl-2,3-dihydro-1,4-diazepines
A series of 5-per(poly)fluoroalkyl-2,3-dihydro-1,4-diazepines were synthesized from α-per(poly)fluoroalkyl aldehydes and ethylenediamine. A possible reaction pathway was suggested.
A novel method for preparation of trifluoromethyl substituted 2,3- dihydro-1,4-diazepine and benzimidazole
Ethylenediamine reacted readily with 4-ethoxy-1,1,1-trifluoro-3-butene- 2-one to form 5-trifluoromethyl-2,3-dihydro-1,4-diazepine in good yield. Under the same reaction conditions o-phenylene diamine gave 2-trifluoromethyl benzimidazole and benzimidazole.
