The reaction between alkynes and cyclopropylcarbene-tungsten and molybdenum complexes has been examined. Depending upon the conditions of the reaction, either cycloheptadienones or furanones are obtained. The scope, limitation, and mechanistic rationale for observed selectivities are discussed.

Synthesis of ferrocenyl pyrazoles by the reaction of (2-formyl-1-chlorovinyl)ferrocene with hydrazines Zora, Metin (Elsevier BV, 2007-10-15) Synthesis of ferrocenyl-substituted pyrazoles via the reaction between (2-formyl-1-chlorovinyl)ferrocene and hydrazine derivatives is described. Depending upon the substitution pattern of hydrazine, the reaction affords 1-alkyl/aryl-5-ferrocenylpyrazoles and/or 1-alkyl/ aryl-3-ferrocenylpyrazoles. The reaction appears to be general for a variety of hydrazine derivatives.
Synthesis of new mediators for electrochemical nad/nadh recycling Khalily, Mohammad Aref; Demir, Ayhan Sıtkı; Department of Chemistry (2011) The synthesis of enantiopure compounds can be achieved by using dehydrogenases as biocatalysts. For instance, reduction reactions of prochiral compounds (ketones, aldehydes and nitriles) into chiral compounds can be achieved by dehydrogenases. These dehydrogenases are cofactor dependent where cofactor is Nicotinamide Adenin Dinucleotite having some restrictions that confines usage of dehydrogenases in organic synthesis including instability of cofactor in water and high cost. Therefore, suitable recycling m...
Synthesis of conducting graft copolymers of 2-(N-pyrrolyl)ethylvinyl ether with pyrrole Bengu, B; Toppare, Levent Kamil; Kalaycioglu, E (2001-01-01) 2-(N-pyrrolyl)ethylvinyl ether (2-NEVE) was synthesized from 2-chloroethylvinyl ether (2-CEVE) via a phase catalysis reaction. Cyclic voltammetric studies were carried out to check for the electroactivity of 2-NEVE. Poly(2-(N-pyrrolyl)ethylvinyl ether) [poly(2-NEVE)] was synthesized via chemical methods. Graft copolymers of pyrrole and 2-NEVE were synthesized by electrochemical methods. The chemical structures of 2-NEVE and poly(2-NEVE) were investigated by several spectroscopic methods. Graft copolymers we...
Synthesis and characterization of conducting copolymers of succinic acid bis-(4-pyrrol-1-yl-phenyl) ester and their electrochromic properties Ertas, M; Çırpan, Ali; Toppare, Levent Kamil (Elsevier BV, 2004-05-07) A new dipyrrolyl monomer was synthesized via the reaction between 4-pyrrol-1-yl phenol and butanedioyl dichloride. Electrochemical behavior of this monomer, succinic acid bis-(4-pyrrol-1-yl-phenyl) ester (SM) was studied. Homopolymerization was achieved by chemical and constant Current electrolysis methods. Copolymerization of SM with thiophene was performed by constant potential electrolysis in acetonitrile (AN)-tetrabutylammonium tetrafluoroborate (TBAFB) and dichloromethane (DCM)-TBAFB, solvent-electroly...
Synthesis of chiral acetoxy lactones via the Baeyer-Villiger oxidation of cyclic aromatic acetoxy ketones Demir, Ayhan Sıtkı; Aybey, Asuman (Elsevier BV, 2008-12-01) The alpha-acetoxylation of indanones and tetralones by using Mn(OAc)(3) followed by the enzyme catalyzed kinetic resolution of acetoxy ketones furnished both of the enantiomers of alpha-acetoxy ketones in good chemical and optical yields. The Baeyer-Villiger oxidation of alpha-acetoxy ketones with m-CPBA, CF(3)SO(3)H, and CH(2)O(2), at rt gives the corresponding lactones without racemization. The acetoxy ketone moiety migrates selectively in order to form lactones. The mild hydrolysis of lactones affords ph...
