Cs2CO3-Promoted C?O Coupling Protocol Enables Solventless (Hetero)aryl Ether Synthesis under Air Atmosphere

In this work, a Cs2CO3-promoted synthetic approach was identified for (hetero)aryl ether synthesis via the C?O coupling of various (hetero)aryl chlorides and alcohols/phenol. To our delight, the reactions could be carried out under transition-metal-free and solvent-free conditions. Moreover, analytical-grade reagents and air atmosphere were readily tolerated. To showcase the practical usefulness of the present protocol, the assembly of a bioactive molecule was facilely realized and the gram-scale production of selected ether products was also efficiently accomplished. In addition, density functional theory (DFT) studies, along with a few mechanistic experiments, were conducted to elucidate a proposed reaction pathway and rationalize the pivotal role of Cs2CO3 in promoting this process. Hopefully, this work could provide useful information for researchers who are engaging in C?O cross-coupling reactions.

Copper(I)-catalyzed cascade synthesis of 2-substituted 1,3-benzothiazoles: Direct access to benzothiazolones

An efficient cascade process for the preparation of 2-substituted 1,3-benzothiazoles directly from 2-haloaryl isothiocyanates and O or S nucleophiles by a Cu-catalyzed, intramolecular, C-S bond formation has been developed. This cascade method is viable f

Process for synthesizing thiacyanine dyes

There is described a process for synthesizing a thiacyanine dye wherein a 2-halo, 2-alkoxy or 2-aryloxybenzothiazole is alkylated by a strong alkylating agent to form a quaternized benzothiazole which, without being isolated, is condensed with a benzothiazolium betaine in a nonaqueous homogeneous medium. The thiacyanine dye is useful for enhancing the photosensitivity of a blue-sensitive silver halide emulsion.
