註釋Investigations of ligands capable of donating/accepting hydrogen bonds in important catalytic applications were undertaken. It has been found that heterocyclic phosphine ligands, namely 2-pyridyl and 2-imidazolyl phosphines, greatly influence the reactivity of CpRu catalysts. This has led to highly efficient anti-Markovnikov hydration of a variety of terminal alkynes, including aryl alkynes and trimethylsilyl alkynes. Enzyme-like rate enhancements of>109 have facilitated experimental and computational mechanistic studies, supporting multipoint cooperativity involving the metal and the heterocyclic phosphine ligands.
