Cyclopalladated Complexes in Organic Synthesis

Various applications of cyclopalladated compounds to organic syntheses are reviewed. Reactions of the complexes with alkenes, alkynes, carbon monoxide, isocyanides, halogens, acid chlorides. organolithium or Grignard reagents, etc., provide routes to a variety of 1,2-disubstituted aromatic and pseudo-aromatic molecules, heterocycles, and other products. 1.
