Abstract: The Ru(0)-catalyzed straightforward synthesis of conjugated tetraenes has been achieved in up to 85% yield by coupling of 2 equiv of internal alkynes with 1,3-butadiene at room temperature. The stoichiometric reaction of [Ru(η4-cisoid-1,3-butadiene)(η4-1,5-COD)(NCMe)] with 2… read more here.

Abstract: A straightforward Rh(iii)-catalyzed general strategy was developed for the introduction of naphthol/phenol moieties to the C(sp3)-H bond of 8-methylquinoline using diazonaphthalen-2(1H)-ones/quinone diazides. The developed method was further extended towards the arylation of 8-formylquinolines to accomplish… read more here.
