of the most frequently used transformations in organic synthesis. Herein, we developed a novel ruthenium nanoparticle embedded ordered mesoporous carbon catalyst (Ru–OMC) and a new hydrosilylation process for the synthesis of tertiary amines. We present a direct reductive amination of imines (CN bond) with aldehydes (CO bond) using hydrosilane as the reducing reagent under mild conditions. Moreover,

When thienyl Schiff base 1 reacted with Fe-2(CO)(9) under very mild conditions in benzene three major products were obtained: (1) a cyclometalated (mu-eta(1):eta(2)-thienyl; eta(1) eta(1)(N))-hexacarbonyldiiron complex, 2, (2) a hexacarbonyldiiron complex with an organic ligand, which is composed of two thienyl moieties derived from the original thienyl imine and coupled together by a C-C bond, 3, and (3) a hydrogenation product of the original thienyl Schiff base. Molecular structures of compounds 2b and 3a have been determined by single-crystal X-ray diffraction.
