A series of 1,5-arylodiazepin-2-ones is prepared by the condensation of the approptiate o-β-arylenediamines with β-ketoesters in xylene under microwave irradiation.The reaction time is shortened to 10 mn, and the products are obtained in high yields.No by products are observed.Specific effects of microwaves are evidenced as no reaction occurs by classical heating in same conditions. - Key Words: Condensation; Microwave; 1,5-Arylodiazepin-2-ones.

A number of bis-1,n- alkanes have been prepared by reaction between 4-phenyl (4-cyclopropyl and 4-methyl)-2,3-dihydro 1,5-benzodiazepine 2-one and dihalogenoalkanes X-(CH2)n-X under phase transfer catalysis conditions.The action of hydrazine at different concentration on this structure have been studied.These products have been characterized by NMR 1H, IR, MS and the microanalysis.
