Ruthenium complex-catalysed highly selective codimerisation of acetylenes and alkenes

Abstract
2,4-Dienes are prepared in high yields with high regioselectivity by the codimerisation of acetylenes and alkenes in the presence of a catalytic amount of Ru(cod)(cot) at 80 °C cod = cycloocta-1,5-diene, cot = cycloocta-1,3,5,-triene.
