Abstract: The present invention relates to a catalyst system for preparing a carbonate derivative, comprising selenium (Se) and a pyridine amine compound represented by structural formula 1. The catalyst system for preparing a carbonate derivative, and a method for preparing a carbonate derivative by using same, of the present invention, allow an alcohol to undergo oxidative carbonylation by using a selenium-based catalyst system, and thus are more economical than a conventional carbonylation process and can obtain a dialkyl carbonate in feasible yields.
