Diethylene glycol-functionalized imidazo[1,5-a]pyridin-3-ylidenes (DEG-ImPy) have been developed as bifunctional N-heterocyclic carbene ligands. The DEG-ImPy Cu(i) complexes efficiently catalyzed the direct C-H carboxylation of benzoxazole with CO2, showing higher isolated yields than those with the N,N′-(2,6-diisopropylphenyl)imidazolylidene Cu catalyst.

We investigated new highly conductive polyaniline copolymers bearing a small amount of dual-functional hydrophilic dioxyethylene side chains, which can act as a stabilizer in a heterogeneous dispersion medium in polymerization and a reactive dispersant in polar solvents. Compared to the unsubstituted polyaniline, new polyaniline copolymers maintained their high electrical conductivity of 485 S/cm with camphorsulfonic acid dopant in m-cresol. Moreover, in the alcoholic butoxyethanol solvent with a dodecylbenzenesulfonic acid dopant, new polyaniline copolymers showed enhanced dispersion abilities with very small particle sizes of -6~1 S/cm). Therefore, new polyaniline copolymers are very interesting materials for electronic applications.
