Cyclopentadienone Iron Tricarbonyl Complexes-Catalyzed Hydrogen Transfer in Water

The development of efficient and low-cost catalytic systems is important for the replacement of robust noble metal complexes. The synthesis and application of a stable, phosphine-free, water-soluble cyclopentadienone iron tricarbonyl complex in the reduction of polarized double bonds in pure water is reported. In the presence of cationic bifunctional iron complexes, a variety of alcohols and amines were prepared in good yields under mild reaction conditions.

A phosphine-free iron complex-catalyzed synthesis of cycloalkanes via the borrowing hydrogen strategy

Herein we report a diaminocyclopentadienone iron tricarbonyl complex catalyzed synthesis of substituted cyclopentane, cyclohexane and cycloheptane compounds using the borrowing hydrogen strategy in the presence of various substituted primary and secondary 1,n diols as alkylating reagents.

Synthesis and applications to catalysis of novel cyclopentadienone iron tricarbonyl complexes

New approaches to enantiomerically-pure cyclopentadienone iron complexes, and their applications to ketone reductions reactions, are described.
