umpolung. In the presence of Pd catalyst/P-ligand, the propargyl alkylation reaction complements the traditional coupling of nonstabilized nucleophiles with propargylic electrophiles by employing carbonyls as a source of umpolung alkyl carbanions and surrogates of alkyl organometallicreagents. In dienylation chemistry, the use of the Pd–NHC combination regulated the product distribution, thus providing
