NCN-pincer Ru-complexes containing bis(oxazolinyl)phenyl ligands serve as suitable catalysts in the direct conjugate additions of α,β-unsaturated carbonyl compounds, including ketones, esters, and amides, as well as vinylphosphonates, giving various β-alkynyl carbonyl and phosphonate compounds. A bis(oxazolinyl)phenyl (phebox)-Ru complex also catalyzes the asymmetric conjugate addition of an alkyne with a β-substituted, α,β-unsaturated ketone to produce a chiral β-alkynyl ketone.
含双（恶唑啉基）苯基配体的 NCN-夹 Ru 配合物可用作直接共轭加成 α,β-不饱和羰基化合物（包括酮、酯和酰胺）以及乙烯基膦酸酯的合适催化剂，生成各种 β-炔基羰基和膦酸酯化合物。双（恶唑啉基）苯基（phebox）-Ru 配合物也可催化炔烃与 β-取代的 α,β-不饱和酮的不对称共轭加成，生成手性 β-炔基酮。
