A single-step synthesis of 4-hydroxy-functionalized bi-aryl and aryl/alkyl ketones via oxidative coupling of terminal alkynes with benzoquinones is reported. Furthermore, with naphthoquinones, owing to the cross-resonance of carbonyl with the aromatic ring, alkene-alkyne cycloaddition is more favored to give four-membered carbocyclic adducts, thereby precluding the requirement of preactivated alkynes.
MESOGENIC AND NON MESOGENIC CENTRAL RIGID CORES.

The mesogenic power of several central rigid cores is measured by means of depolarized Rayleigh scattering. It is shown that there is a close relation between the angular correlation parameter J and the mesogenic power that lead us to define mesogenic and
