Abstract: The present invention relates to a process for carbonylation of epoxide derivatives, in which the reactivity, selectivity and the yield are superior. More specifically, the present invention relates to a process for hydroformylation of an epoxide derivative in which there is utilized a transition metal catalyst having a cyclopentadienyl radical, thereby improving the reactivity and selectivity. Further, the present invention relates to a process for hydroesterification of an epoxide derivative, in which a proper catalyst is selected, and the reaction temperature and pressure are adjusted within proper ranges under the presence of a cobalt catalyst, thereby improving the product selectivity and the yield.

Abstract: The metallocene complexes according to the present invention are prepared by reacting a transition metal complex of Group III-X of the Periodic Table, having at least one cycloalkanedienyl group, with a compound having at least two functional groups. The transition metal complex has a main ligand such as a cycloalkanedienyl group and at least one ancillary ligand which coordinated to a transition metal of Group III-X. The functional groups in the compound having at least two functional group are selected from the group consisting of a hydroxyl group (—OH), a thiol group (—SH), a primary amine group (—NH2), a secondary amine group (RNH—), a tertiary amine group (RR′N) a primary phosphorous group (—PH2), a secondary phosphorous group (RPH—), a tertiary phosphorous group (RR′P), a thiirane group etc.
