Cyclopentene is shown to be an ideal substrate for coupling reactions with (Lig)nickel(0) systems. By variation of the ligands and addition of promoters, it is possible by successive application of carbon dioxide or carbon monoxide to prepare highly selectively series of cyclopentane- and cyclopentenecarboxylic acids (six examples), 4, 5, 6, 11, 14, 15, cyclopentanedicarboxylic acids (three examples), 7, 8, 12, or 2-hydroxycyclopentanecarboxylic acid (9) in good yields. The C5-skeleton is retained in the products.
