Preference for β-H Elimination in the Termination of the Ni-Promoted Carbonylative Cycloaddition of 2-Haloethylidene-cycloalkanes and Alkynes. -In the Ni(CO) 4 -mediated carbonylative cycloaddition of alkynes and 2-haloethylidenecycloalkanes, the terminating step consists almost exclusively of a β-hydride elimination affording 5-cycloalkylidene-2cyclopentenones or 5-(1-cycloalkenyl)-2-cyclopentenones. -(VILASECA, F.;
