Direct C–H alkylation of aldehydes represents a straightforward and step-economy strategy for modular access to ketones. Herein, we report a direct C–H alkylation of aldehydes with alkyl bromides to generate ketones under cooperative NHC/Pd catalysis at room temperature. Secondary and the difficult-to-obtain tertiary alkyl-derived ketones could be prepared through this simple process under mild conditions
