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.
