The present invention relates to (2-cyclopentenyl)chlorosilane derivatives and the preparation method thereof. In particular, it relates to a very economical process which reacts cyclopentadiene, which is formed by a cracking of industrially produced low-priced dicyclopentadiene, with a silane compound containing silicon-hydrogen bonds at elevated temperature in a hydrocarbon compound with a boiling point of a predetermined range, thus also enabling to prevent problematic production of dicyclopentadiene polymer by using the hydrocarbon compound. Further, in the presence of a group 10 metal compound catalyst, the process herein is capable of lowering the reaction temperature and increasing the yield in the reaction of sterically hindered alkyl-dichlorosilane. The (2-cyclopentenyl)chlorosilane may be useful in preparing an organic silicon compound containing an unsaturated group or a functional silicone polymer using the same, or in modifying the surface or manufacturing a thin layer.
A cyclopentenyl chlorosilane derivative of formula (1):
A process of preparing a cyclopentenylchlorosilane derivative of Formula (1), the process comprising a step of performing a reaction with dicyclopentadiene and an organic silane compound of Formula (2) at an elevated temperature:
