An easy and fast one-pot preparation of 2-thiomethyl and 2-thioacyl benzothiazoles, benzoxazoles, and benzimidazoles
Quaternary 2-thiomethylbenzazoles are important class of intermediates involved in the synthesis of symmetric and asymmetric monomethine cyanine dyes. In addition to, 2methylmercaptobenzothiazole, and 2methylmercaptobenzoxazole derivatives represent an essential group of compounds for the synthesis of cyanine dyes [1–3]. S-Alkylated heterocyclic derivatives are known as key compounds, finding a...
متن کاملRoom temperature and solvent-free iridium-catalyzed selective alkylation of anilines with alcohols.
A bidentate iridium NHC-phosphine complex has been developed and applied to the N-monoalkylation of aromatic amines with a wide range of primary alcohols and to the N-heterocyclization of amino alcohols. This reaction resulted in high isolated product yields, even at room temperature and under solvent-free conditions.
متن کاملSelective oxidations of activated alcohols in water at room temperature.
Allylic and benzylic alcohols can be selectively oxidized to their corresponding aldehydes or ketones in water containing nanoreactors composed of the designer surfactant TPGS-750-M. The oxidation relies on catalytic amounts of CuBr, bpy, and TEMPO, with N-methyl-imidazole; air is the stoichiometric oxidant.
متن کاملAn air stable and efficient palladium catalyst for Suzuki-Miyaura cross coupling reaction at room temperature
The cross-coupling reaction between phenylboronic acid and various types of aryl halides (Suzuki reaction) was carried out using a catalytic amount of a new palladium catalyst (1-benzyl-3-(1-benzyl-1-methylpyrrolidin-1-ium-2-yl) pyridin-1-ium palladium chloride [DBNT][PdCl4]) in poly (ethylene glycol) (PEG-200) in the presence of KOH as the base. This new catalyst was synthesized and...
