Synthese et reactivite de nouvelles molecules de type bis--1,n alcanes

Achour, Redouane,Essassi, El Mokhtar,Zniber, Rachid

, p. 889 - 896 (2007/10/02)

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.
