A homogeneous catalytic reaction method and a catalyst for isomerization and hydroformylation of long-chain internal olefins are disclosed. A rhodium-ruthenium metal complex is used as a catalyst; and the ligands are tetradentate phosphine ligands. By means of the catalytic system, homogeneous internal olefin isomerization aid hydroformylation can be performed under a certain temperature and pressure to obtain aldehyde products having high normal to iso ratios. The present invention is applicable to not only long-chain internal olefins (C8) but also internal olefins having a carbon number less than 8.

The present invention is in the field of processes for the generation of thin inorganic films on substrates, in particular atomic layer deposition processes. It relates to a process for preparing metal films comprising (a) depositing a metal-containing compound from the gaseous state onto a solid substrate and (b) bringing the solid substrate with the deposited metal-containing compound in contact with a reducing agent in the gaseous state, wherein the reducing agent is or at least partially forms at the surface of the solid substrate a carbene, a silylene or a phosphor radical.
