The electrophile-electrophile cross-coupling of carboxylic acid derivatives and alkylpyridinium salts via C-N bond cleavage is developed. The method is distinguished by its simplicity and steers us through a variety of functionalized ketones in good to excellent yields. Besides acid chlorides, carboxylic acids were also employed as acylating agents, which enabled us to incorporate acid-sensitive functional groups such as MOM, BOC, and acetal. Control experiments with TEMPO revealed a radical pathway.
Synergistic Photoredox/Nickel Coupling of Acyl Chlorides with Secondary Alkyltrifluoroborates: Dialkyl Ketone Synthesis

Visible light photoredox/nickel dual catalysis has been employed in the cross-coupling of acyl chlorides with potassium alkyltrifluoroborates. This protocol, based on single-electron-mediated alkyl transfer, circumvents the restriction of using reactive alkylmetallic nucleophiles in transition-metal-catalyzed acylation and achieves a mild and efficient method for the synthesis of unsymmetrical alkyl ketones. In this approach, a variety of acyl chlorides have been successfully coupled with structurally diverse potassium alkyltrifluoroborates, generating the corresponding ketones with good yields.
LITHIUM TRIS(PHENYLTHIO)METHANE FOR THE HOMOLOGATION OF TRIALKYLBORANES: CONVENIENT SYNTHESES OF KETONES AND t-CARBINOLS
Pelter, Andrew,Rao, J. Madhusudhana
, p. 65 - 70 (2007/10/02)
Lithium tris(phenylthio)methane is a readily available, cheap reagent for the production of ketones and t-carbinols from trialkylboranes.The scope and limitations of the reactions are indicated as are some of its unique features.
