Abstract
In the presence of catalytic amounts of GaCl3 (10 mol%) and 2,6-di(t-butyl)-4-methylpyridine (10 mol%), five- or six-membered ring ketones possessing α,α′-disubstituents are ethenylated at the α-carbon with triethylsilylethyne at 180°C. The roles of the base are to inhibit decomposition of the products and to promote proto-degallation of the organogallium intermediates.
