The phenomenon of β-phenyl quenching has been examined by laser-flash photolysis in a series of α- and/or β-substituted ketones 4-8 with similar excited-state characteristics. It is found that α-substitution markedly increases the triplet lifetimes in con

A simple Lewis acid-mediated route for the synthesis of alkenyl halides are described under microwave-assisted conditions. The reaction proceeds through the condensation between secondary alcohols and terminal acetylenes and regioselective hydrohalogenati

The syntheses of β,β-diaryl aryl propiophenones have been realized via palladium-catalyzed domino reactions of dimethyl amino functionalized enaminones and aryl boronic acids. This is the first example of transition metal-catalyzed enaminone C-N bond conversion for the generation of a new C-C(aryl) structure.
