The first structural characterisation of ruthenium and rhodium complexes of the 1,1′‐bis(phosphetano)ferrocenes 1 (FerroTANEs) − namely [{( S , S )‐ i Pr‐ 1 }RuCl 2 Py 2 ] and [{( S , S )‐ i Pr‐ 1 }Rh(COD)OTf] − is reported. X‐ray data show that the ruthenium complex and the rhodium chelate complex both adopt δ conformations, as a result of the ( S , S ) configuration of the phosphetane moiety. The ruthenium complexes promote the catalytic hydrogenation of β‐keto esters with moderate to high enantioselectivities. The behaviour of the rhodium complexes of 1 is compared with that of other phosphetane‐based catalysts in the hydrogenation of methyl N ‐acetamidocinnamate. (© Wiley‐VCH Verlag GmbH & Co.
