The asymmetric codimerization of cyclohexa-1, 3-diene with ethylene is catalysed by the Ni (cyclo-octa-1, 5-diene)–AlEtCl–L system where L are chiral aminophosphines; optimization of this catalytic system (–70° C; L/Ni= 10) gives (+)-()-3-vinylcyclohexene with 73· 5% optical purity in 87% chemical yield when (–)-()--me
