摘要： This invention provides a hydrosilylation method in which hydrosilyl groups are added to olefin using a metal catalyst, which comprises controlling the hydrosilylation reaction by allowing a compound selected from thiazoles and phosphines to coexist in the reaction system, and a process making use thereof for the production of a hydrosilyl group-containing organic curing agent. This invention gives a method for easy control of hydrosilylation reaction and a process making use thereof for the production of an organic compound modifying silicon compound having 2 or more hydrosilyl groups in the molecule. This compound is used as a curing agent of addition type curable compositions. As an accompanying effect, storage stability of the produced curing agent is improved when a catalyst and additives of this invention remain therein, in comparison with the case in which only the catalyst remains.
