Iridium complexes show high catalytic activity in intermolecular additions of acid chlorides to terminal alkynes to afford valuable (Z)-β-chloro-α,β-unsaturated ketones. Ligands in the catalytic system play a crucial role in this reaction. An N-heterocyclic carbene (NHC) is an efficient ligand

This paper describes a Rh(I)-catalyzed highly efficient and enantioselective 1,2-addition of arylboronic acids to α-diketones with the use of a simple sulfur-alkene hybrid ligand. With as low as a 0.1 mol % catalyst loading, a variety of optically active α-hydroxyketones

A "build/couple/pair" pathway for the systematic synthesis of structurally diverse small molecules is presented. The Petasis 3-component reaction was used to synthesize anti-amino alcohols displaying pairwise reactive combinations of alkene moieties. Upon treatment with a ruthenium alkylidene-catalyst, these dienes selectively
