Selective dimerization of 1,6-diynes catalyzed by ionic liquid-supported nickel complexes in an ionic liquid/toluene biphasic system.
A NiCl(2)-6H(2)O/Zn reagent with a 2-aryliminomethylpyridine ligand catalyzed cyclization/polymerization of 1,6-diynes to yield mainly the corresponding poly(1,3-butadienylene) compounds, whereas NiBr(2)-3H(2)O/Zn with the use of 3-(2-(2-methoxyethoxy)-ethyl)-1-methyl-1H-imidazol-3-ium bromide as a ligand converted 1,6-diynes to the corresponding annulated 1,3,5,7-cyclooctatetraenes in a biphas...
متن کاملPolymer-supported basic ionic liquid as an efficient heterogeneous catalyst system for straightforward synthesis of flavanones
Aromatic aldehydes are efficiently condensed with 2'-hydroxyacetophenone by polymer-supported basic ionic liquid as an excellent heterogeneous catalyst utilizing the Claisen–Schmidt reaction. Microwave irradiation has been employed, providing flavanone in good yield and short reaction time.
