Novel metal-free and metallophthalocyanines containing four 21-membered pentathiadiaza macrocycles: synthesis, characterization, and study of aggregation properties
Gök, Halil Zeki; Farsak, Berna; Keleş, Hülya; Keleş, Mustafa (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2014)Metal-free phthalocyanine 3 and its metallophthalocyanine derivatives 4, 5, and 6 (M = Zn, Co, and Ni) substituted with four 21-membered pentathiadiaza macrocycles were synthesized and their structures identified by elemental ... -
Synthesis of C 2 -symmetric bisphosphines and their application in enantioselective transition metal catalysis
Gök, Halil Zeki; Kılıçarslan, Seda; Gök, Yaşar (Croatian Chemical Society, 2018)C2-symmetric bisphosphine ligands (with a dioxolane backbone) have been synthesized by using corresponding chiral bromo-substituted hydrobenzoin derivatives in two steps with moderate yields. The last step for desired ... -
Synthesis of metal-free and metallophthalocyanines containing 18-and 21-membered macrocycles with mixed donor atoms and their metal-ion binding properties
Gök, Halil Zeki (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2015)This paper describes the synthesis of a series of metal-free phthalocyanines and metallophthalocyanines peripherally substituted by macrocycles of different ring sizes with the same donor atom sets. The effects of varying ... -
Synthesis, characterization, and metal extraction studies of a new macrobicyclic ligand
Gök, Halil Zeki; Gök, Yaşar; Eker, Esra (SCIENTIFIC TECHNICAL RESEARCH COUNCIL TURKEY-TUBITAK, 2015)This article describes the synthesis, characterization, and metal ion binding properties of a new macrobicyclic ligand. Solvent extraction experiments were performed in order to determine the extraction behavior of new ...
