Abstract

Abstract Diketones are regioselectively prepared from alkynyl ketones under mild conditions by palladium catalysis; 5-heptyn-2-one and 2-(2-nonynyl) cyclohexanone give 1, 4- dikektones whereas 2-(2-heptynyl) cyclopentanone and 5, 6-didehydroprostaglandin E 2 methyl ester afford 1, 5-diketones.
