Abstract
New fluorenyl silane compounds and method for their production are disclosed. The fluorenyl compounds have the formula ##STR1## wherein Z is a substituted or unsubstituted fluorenyl radical and Z' is a substituted or unsubstituted cyclopentadienyl-type radical or a halogen.
Claims34
A compound of the formula ##STR14## wherein Z is a substituted or unsubstituted fluorenyl;
- Z' is selected from the group consisting of unsubstituted fluorenyl, substituted fluorenyl, unsubstituted cyclopentadienyl, substituted cyclopentadienyl, unsubstituted indenyl, substituted indenyl, tetrahydroindenyl, and halides;
- and each R' is individually selected from the group consisting of hydrogen and organo radicals having 1 to 40 carbon atoms further characterized by the fact that if Z' is a halide and each R' is alkyl, then Z is a substituted fluorenyl, and if Z' is not a halide, and both R's are alkyl or phenyl, or one R' is phenyl and the other is fluorenyl and Z is unsubstituted, then Z' is selected from the group consisting of substituted fluorenyl, unsubstituted cyclopentadienyl, substituted cyclopentadienyl, unsubstituted indenyl, and tetrahydroindenyl.
A method for preparing a compound of the formula ##STR15## wherein each Z is the same substituted or unsubstituted fluorenyl radical and each R' is individually selected from the group consisting of hydrogen and organo radicals containing 1 to 40 carbon atoms, comprising reacting the precursor for the Z fluorenyl radical with an alkali metal alkyl under suitable conditions to produce the corresponding Z anion and contacting said Z anion under suitable conditions with a dihalosilane of the formula ##STR16## wherein each X is individually selected from Br, Cl, or I and R' is as defined above, said suitable conditions including limiting the solvents employed to non-polar solvents.
