Ruthenium-Catalyzed Propargylic Reduction of Propargylic Alcohols with Hantzsch Ester

Ruthenium-catalyzed propargylic reduction of propargylic alcohols bearing a terminal alkyne moiety is accomplished by using Hantzsch ester as a nucleophilic hydride source. A variety of secondary and tertiary propargylic alcohols are reduced to the corresponding propargylic reduced products such as 1-alkynes in excellent yields. Some mechanistic studies indicate that ruthenium-allenylidene complexes may work as key reactive intermediates.

Preparation of thiolate-bridged dinuclear ruthenium complexes bearing a phosphine ligand and application to propargylic reduction of propargylic alcohols with 2-propanol

Novel thiolate-bridged dinuclear ruthenium complexes bearing a phosphine ligand, [CpRu{PhP(C6H4-o-S)2}RuCp](OTf) 2, [CpRu{PhP(C6H4-o-S)2}RuCp(OH 2)](OTf)2, and [CpFe{PhP(C6H 4-o-S)2}RuCp](OTf)2, are prepared and characterized by X-ray analysis. These dinuclear complexes work as effective catalysts toward propargylic reduction of propargylic alcohols with 2-propanol via allenylidene complexes as key intermediates to give the corresponding alkynes in good to high yields.
