The present invention provides a silacyclopentadiene derivative represented by the following Formula (1): ##STR1## wherein X.sub.1 and Y.sub.1 represent independently a halogen atom, an amino group, a hydroxyl group, or an amino group or a hydroxyl group each having a substituent; R.sub.1 to R.sub.4 represent independently a hydrogen atom, a halogen atom, an alkyl group, an amino group, a silyl group, an aryl group, a cyano group, or the respective groups describe above each having a substituent; out of the groups represented by R.sub.1 to R.sub.4, those adjacent may be combined with each other to form rings; when R.sub.1 and R.sub.4 are phenyl groups or when combined are R.sub.1 with R.sub.2 and R.sub.3 with R.sub.4 respectively to form benzene rings, X.sub.1 and Y.sub.1 are not a chlorine atom or a hydroxyl group; and when R.sub.1 and R.sub.4 are methyl groups, X.sub.1 and Y.sub.1 are not bromine atoms.
本发明提供了一种由以下式(1)表示的硅环戊二烯衍生物:##STR1## 其中,X1和Y1分别独立地表示卤素原子、氨基基团、羟基或带有取代基的氨基基团或羟基;R1至R4分别独立地表示氢原子、卤素原子、烷基、氨基基团、硅基基团、芳基基团、氰基或上述各自带有取代基的基团;在由R1至R4表示的基团中,相邻的基团可结合形成环;当R1和R4为苯基或当R1与R2结合,R3与R4结合分别形成苯环时,X1和Y1不是氯原子或羟基;当R1和R4为甲基时,X1和Y1不是溴原子。
