ABSTRACT:
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.
