REACTION OF ARYL- AND HETEROARYL BENZOYL- AND ACETYLHYDRAZONES WITH PHENYLISOCYANATE SYNTHESIS OF SUBSTITUTED-2,3-DIHYDRO-1,3,4- OXADIAZOLES
(الجامعة الإسلامية - غزة, 2006)Aryl benzoylhydrazones (1a-c) react readily with phenylisocyanate (2) at room temperature to give the corresponding substituted 2,3-dihydro-1,3,4-oxadiazoles (3a-c). On the other hand, the reaction of benzoylhydrazones of ... -
Reaction of aryl-and heteroaryl benzoyl-and acetylhydrazones with phenylisocyanate synthesis of substituted-2, 3-dihydro-1, 3, 4-oxadiazoles
(2016)Aryl benzoylhydrazones (1a-c) react readily with phenylisocyanate (2) at room temperature to give the corresponding substituted 2, 3-dihydro-1, 3, 4-oxadiazoles (3a-c). On the other hand, the reaction of benzoylhydrazones ... -
SYNTHESIS AND X-RAY CRYSTAL STRUCTURE ANALYSIS OF SUBSTITUTED 2,3-DIHYDRO-1,3,4-OXADIAZOLES VIA REACTION OF ACETONE- AND CYCLOALKANONE BENZOYLHYDRAZONES WITH PHENYLISOCYANATE
(الجامعة الإسلامية - غزة, 2005)Oximic 1,2,4-triazole ligands 2a-e were prepared from the reaction of 3-acetyl–4,5-dihydro-1H-1,2,4-triazoles 1a-e with hydroxylamine hydrochloride at room temperature. At higher temperatures, the reaction afforded, however, ...
