In this review we report our development and applications of the highly selective cycloaddition reactions of unsaturated hydrocarbons such as conjugated enynes, electron-deficient allenes, and electron-deficient methylenecyclopropanes in the presence of nickel and palladium catalysts. Homocoupling reactions as well as co-cyclization reactions proceed with high atom economy, which is an attractive feature of these reactions. The efficient synthesis of 4-7 membered carbocycles was achieved.
