elimination-demanding Pd-catalyzed mono-α-arylation of acetone is demonstrated and reported. The catalyst is tolerant of previously proven challenging electron-deficient aryl chlorides and provides excellent product yields with down to 0.1 mol % Pd. Preliminary investigations suggest that the rate-limiting step for the proposed system is the oxidative addition of aryl chlorides, in which it contradicts

selective Pd-catalyzed mono-α-arylation of acetone employing aryl chlorides, bromides, iodides, and tosylates. The use of appropriately designed P,N-ligands proved to be the key to controlling the reactivity and selectivity. The reaction affords good yields with substrates containing a range of functional groups at modest Pd loadings using Cs(2)CO(3) as the base and employing acetone as both a reagent and

A monomer having a substituent group capable of polarity switch under the action of acid is provided. A useful polymer is obtained by polymerizing the monomer. A resist composition comprising the polymer has improved development properties and is processed to form a negative pattern having high resolution and etch resistance which is insoluble in alkaline developer.
