N-Heterocyclic carbene copper(I) complex-catalyzed synthesis of 2-aryl benzoxazoles and benzothiazoles
(2016)
A new and efficient synthesis of 2-arylbenzoxazoles and benzothiazoles using a copper N-heterocyclic carbene complex is described. In a simple protocol a variety of 2-substituted benzoxazoles and benzothiazoles were obtained ...
Thermohalochromism of phenolate dyes conjugated with nitro-substituted aryl groups
(2017)
The cationic halochromism and thermohalochromism of four phenolate dyes conjugated with aryl moieties substituted with one or two nitro groups were investigated in the presence of organic (tetra-n-butylammonium bromide and ...

Sonochemical synthesis of bis(tri-n-butylstannyl) aromatic compounds via Barbier-like reactions
(Elsevier, 2013-05-24)
This paper reports a study of the synthesis of aryltri-n-butylstannanes via a sonochemical Barbier reaction of aryl- and heteroaryl bromides with bis(tri-n-butyltin) oxide (2) in THF. Our results demonstrate that, despite ...

Dicyclohexylphosphino cyrhetrene: synthesis, characterization and catalytic evaluation toward suzuki-miyaura cross-coupling reaction of aryl bromides and chlorides
(2018)
Reaction of cyrhetrene ((eta(5)-C5H5)Re(CO)(3)) with n-butyllithium (1.0 equiv, -78 degrees C) and then CIPCy2 (Cy = cyclohexyl) gives the new cyrhetrenyl-phosphino ligand (eta(5)-C5H4PCy2)Re(CO)(3) which was isolated as ...
