摘要:
Cyclooctene and 1,5-cyclooctadiene are shown to be ideal substrates for coupling reactions with CO2 on (Lig)Nickel(0)-systems. By variation of the ligands and addition of promoters, it is possible by successive application of carbon dioxide, carbon monoxide, FeCl3 or (CH-3)3N --> O to prepare highly selectivity series of cyclooctane- and cyclooctenecarboxylic acids.
