Effect of immobilization on catalytic characteristics of saturated Pd-N-heterocyclic carbenes in Mizoroki-Heck reactions Aksın, Özge; Türkmen, Hayati; Artok, Levent; Çetinkaya, Bekir; Ni, Chaoying; Büyükgüngör, Orhan; Özkal, Erhan (Elsevier, 2006-06)A saturated Pd-N-heterocyclic complex was immobilized on an amorphous silica. The complex itself is of very high thermal stability. However, TEM observations, hot filtration, reusability, and poisoning tests all revealed ...
Pd-loaded NaY zeolite as a highly active catalyst for ligandless Suzuki-Miyaura reactions of aryl halides at low Pd loadings under aerobic conditions The Pd(NH3)42+-loaded NaY zeolite was found to be a highly active catalyst precursor for Suzuki-Miyaura (SM) reactions of aryl bromides and aryl chlorides at low Pd concentrations in air. Aryl bromides and arylboronic acids ...
Rhodium catalyzed reaction of internal alkynes with organoborons under CO atmosphere: a product tunable reaction Artok, Levent; Kuş, Melih; Aksın, Özge; Dege, Fatma Nurcan; Özkılınç, Fatma Yelda (Elsevier, 2009-11)Alkynes react with organoborons under a CO atmosphere in the presence of a rhodium(I) catalyst to afford mainly 5-aryl-2(5H)-furanones, α,β-unsaturated ketones, and indanones. The product selectivity can be tuned by modifying ...
Rhodium-catalyzed carbonylative arylation of alkynes with arylboronic acids: An efficient and straightforward method in the synthesis of 5-aryl-2(5H)-furanones Aksın, Özge; Dege, Nurcan; Artok, Levent; Türkmen, Hayati; Çetinkaya, Bekir (Royal Society of Chemistry, 2006)5-Aryl-2(5H)-furanones can be synthesized by the Rh-catalyzed reactions of arylboronic acids with internal alkynes under a CO atmosphere.
