An organic silicon compound represented by the following general formula: ClCH2CH(CF3)COOR3Si(R1)n(R2)3-n (wherein, R1 independently designates the same or different substituted or unsubstituted hydrocarbon groups having 1 to 20 carbon atoms, R2 independently designates the same or different groups selected from halogen groups or hydrolysable groups having 1 to 20 carbon atoms, R3 designates substituted or unsubstituted alkylene groups having 1 to 20 carbon atoms, and “n” is an integer from 0 to 3). The organic silicon compound is suitable for use as a preferable precursor in the manufacture of silanes that contain (2-trifluoromethylacryloxy)alkyl groups.
以下是通用公式所表示的有机硅化合物:ClCH2CH(CF3)COOR3Si(R1)n(R2)3-n(其中,R1独立地指代具有1到20个碳原子的取代或未取代的烃基,R2独立地指代从卤素基或可水解基中选择的相同或不同的基团,具有1到20个碳原子,R3指代具有1到20个碳原子的取代或未取代的烷基,而“n”是从0到3的整数)。该有机硅化合物适用于用作制造含有(2-三氟甲基丙烯酰氧基)烷基的硅烷的优选前体。
