experimental part, p. 10134 - 10141 (2010/02/28)
A highly-efficient and practical method for the formation of ynones from a variety of acyl chlorides and terminal alkynes catalyzed by a nanosized MCM-41 anchored palladium bipyridyl complex is described herein. Aroyl, heteroaroyl, and alkyl acyl chlorides were easily coupled with terminal alkynes, giving good to high isolated yields in the presence of a very low catalyst loading (0.002-0.1 mol % Pd) in Et3N or diisopropylethylamine at 50 °C. Furthermore, the reaction scale was up to 150 mmol for a single batch reaction, providing the potential for practically synthetic application. After centrifugation, the supported catalyst was able to be recycled and reused several times with only a slight decrease in activity.

, p. 2071 - 2073 (2007/10/03)
(Chemical Equation Presented) A rhodium-catalyzed addition of arylzinc reagents to aryl alkynyl ketones for the synthesis of highly substituted indanones has been developed. The key to success has proved to be a proper choice of the reaction system, which involves the employment of dppf as a ligand and 1,2-dichloroethane as a solvent.
