An ususual migration of the alkyl group away from the CO bond of added formate leads to strictly stereospecific formation of the stable ehtyl complex 2 when the catalytic addition of ethyl formate to ethylene (catalyst = 1 ) is terminated by freezing. Both ethylene and the alkyl formate act as sources of the alkyl groups and can thus be used for CC bond‐forming reactions below ambient temperature. PPN + = (Ph 3 P) 2 N + .
