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.

Provided are a transition metal compound including a novel carbene compound as a ligand, a preparation method thereof, and an application thereof. The transition metal compound according to the present invention may form a structurally stable complex and also have a HOMO-LUMO energy gap and singlet-triplet transition energy which are significantly low as compared with a conventional transition metal compound. In addition, according to the present invention, the transition metal compound may be synthesized in large quantities by a very simple method, thereby having high commercial utility, and thus, an application using the compound is expected.

The present invention refers to a method for reducing heavy end formation and catalyst loss in a continuous hydroformylation process, where an olefin or an olefin mixture is reacted with carbon monoxide and hydrogen in a reactor assembly (1) in the presence of a rhodium complex catalyst, comprising at least one organobisphosphite ligand, in order to produce an aldehyde. Said method comprising the addition of an epoxide to the reaction mixture and the continuous or discontinuous removal of early heavy ends.
