Controlled synthesis of α-monoarylated ketones is significant yet challenging due to the site-selectivity issues and nonproductive overarylation reactions. Herein, we reported the direct synthesis of α-arylated ketones enabled by Ni-catalyzed dehydrogenative cross-coupling reaction cascade between alcohols and olefins. The use of readily available and cost-effective alcohols and olefins provides a
N-neopentyl group and seven-membered backbone structure was achieved through the use of aliphatic aldehydes as acyl donors in the decarboxylative radical coupling with aliphatic carboxylic acid derived-redox active esters. The NHC catalyst also enabled the vicinal alkylacylation of vinyl arenes using aliphatic aldehydes and redox-active esters through a radical relay mechanism. These reactions provided the synthetic

organometallic reagents represents a convergent route toward complex and versatile ketone products. Despite the mild conditions and high functional group tolerance, the cross-coupling of carboxylic acid derivatives, such as thioesters, and secondary organometallic reagents is an underdeveloped transformation. Herein, we disclose a convenient and efficient protocol for the Pd-catalyzed Fukuyama cross-coupling
