A Comparative Study in Oxidative Free Radical Reactions between 9-Benzylidene-9-H Fluorene Derivatives and beta-Dicarbonyl Compounds in the Presence of Mn(OAc)(3) and CAN

Demirhan, Hülya; Arslan, Mustafa; Zengin, Mustafa; Küçükislamoğlu, Mustafa (BENTHAM SCIENCE PUBL LTD, 2011)

The reactions of some 1,3-dicarbonyl compounds with 9-benzylidene-9-H-fluorene derivatives in the presence of manganese(III) acetate and ceric ammonium nitrate (CAN) were searched. 9-benzylidene-9-H-fluorene compounds form ...
An efficient one pot synthesis of 1,4-dihydropyridines using alumina sulfuric acid (ASA) catalyst

Arslan, Mustafa; Zengin, Mustafa; Küçükislamoğlu, Mustafa; Demirhan, Hülya (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2009)

An efficient synthetic method for 1,4-dihydropyridines has been developed using 3 or 4 component condensation reactions of aldehydes, 1,3-dicarbonyl compounds, and ammonium acetate in the presence of alumina sulfuric acid ...
Charge transfer complex studies between some non-steroidal anti-inflammatory drugs and pi-electron acceptors

Demirhan, Hülya; Küçükislamoğlu, Mustafa; Zengin, Mustafa (PERGAMON-ELSEVIER SCIENCE LTD, 2006)

Charge transfer (CT) complexes of some non-steroidal anti-inflammatory drugs, naproxen and etodolac which are electron donors with some pi-acceptors, such as tetracyanoethylene (TCNE), 2,3-dichloro-5,6-dicyano-p-benzoquinone ...
Investigation of Charge Transfer Complexes Formed between Mirtazapine and Some pi-Acceptors

Demirhan, Hülya; Arslan, Mustafa; Zengin, Mustafa; Küçükislamoğlu, Mustafa (HINDAWI LTD, 2013)

Charge transfer complexes (CTC) of mirtazapine with tetracyanoethylene (TCNE), 2,3-dichloro-5,6-dicyano-p-benzoquinone (DDQ), and tetracyanoquinodimethane (TCNQ) have been studied spectrophotometrically in dichloromethane ...
