α,β-Unsaturated ketones are valuable prevalent skeletons in organic molecules, which can also be transformed to structurally diverse compounds. Thus far, the efficient construction of α,β-unsaturated ketones via transition-metal-catalyzed direct carbonylative cross-coupling strategies still suffer from limited substrate scope, particularly when constructing alkyl- alkenyl ketones. As such, we herein report a practical nickel-catalyzed stereoretentive carbonylation of tetrasubstituted alkenyl triflates with both primary and secondary alkylzinc pivalates under 101 kPa of CO gas. Moreover, this approach is distinguished by its mild conditions, simple operation, excellent stereoselectivity, and broad functional group compatibility, thereby providing an efficient method for the preparation of α,β-unsaturated ketones.

Key words: alkylcarbonylation, nickel catalyst, α,β-unsaturated ketones, alkylzinc pivalates
