efficient, in situ sequential 1,2-addition of alkyllithium reagents to benzamides followed by α-arylation of the resulting alkylketones is reported. The use of Pd[P(t-Bu)3]2, as catalyst for the α-arylation reaction, allows access to a wide variety of functionalized benzyl ketones in a modular way. The decomposition of the tetrahedral intermediate originated from the 1,2-addition liberates in situ a
