An unexpected dimerization of cyclopropylketones was observed, and analysis of the reaction pathway led to development of a synthetically useful crossed reaction between cyclopropylketones and enones to afford densely functionalized cyclopentane products.

Herein, we report the successful implementation of reductive strategy in the ring opening reaction of aryl cyclopropyl ketones with unactivated alkyl bromides. Under the catalysis of nickel, this reductive Csp3–Csp3 cross-coupling reaction proceeds with complete regioselectivity and bypasses the use of pregenerated organometallics, enabling efficient synthesis of alkylated ketones with high step economy
