Abstract
A Process is disclosed comprising reacting an alkali metal salt of Z with MX.sub.4 to form a trihalo compound; reacting the trihalo compound with an alkali metal salt of Z' to form a dihalo compound; and reacting the dihalo compound with at least one alkali metal organic compound to form Z-MR.sub.2 -Z', where Z is a substituted or unsubstituted fluorenyl radical, M is Ge, Si, or Sn, X is Cl, Br, F, or I, each R is a hydrocarbyl radical containing 1 to 20 carbon atoms, and Z' is an unsubstituted cyclopentadienyl, substituted cyclopentadienyl, unsubstituted indenyl, substituted indenyl, unsubstituted fluorenyl, or a substituted fluorenyl. Also new fluorene compounds are disclosed.

A process comprising:
- (1) reacting an alkali metal salt of Z with MX.sub.4 to produce a trihalo compound,
- wherein Z is an unsubstituted fluorenyl or a substituted fluorenyl, M is Ge, Si, or Sn, and X is Cl, Br, F, or I:
- (2) reacting said trihalo compound with an alkali metal salt of Z' to produce a dihalo compound,
- wherein Z' is an unsubstituted cyclopentadienyl, substituted cyclopentadienyl, unsubstituted indenyl, substituted indenyl, unsubstituted tetrahydroindenyl, substituted tetrahydronindenyl, unsubstituted fluorenyl, or a substituted fluorenyl
- wherein substituents on substituted Z or Z' can be the same or different and are alkyl radicals containing from 1 to 20 carbon atoms;
- and
- (3) reacting said dihalo compound with at least one alkali metal organic compound to produce Z-MR.sub.2 -Z',
- wherein each R is individually selected and is a hydrocarbyl radical containing 1 to 20 carbon atoms.
A process comprising:
- (1) reacting an alkali metal salt of Z with GeCl.sub.4 to produce a trihalo compound,
- wherein Z is an unsubstituted fluorenyl radical;
- (2) reacting said trihalo compound with an alkali metal salt of Z' to produce a dihalo compound,
- wherein Z' is an unsubstituted cyclopentadienyl radical;
- and
- (3) reacting said dihalo compound with at least one alkali metal organic compound to produce Z-GeR.sub.2 -Z',
- wherein each R is an alkyl, cycloalkyl, or aryl radical containing 1 to 8 carbon atoms.
A compound of the formula ##STR6## wherein Z is a substituted or unsubstituted fluorenyl, M is Ge, or Sn, and
- X is Cl, Br, F, or I.
A compound of the formula ##STR7## wherein Z is a substituted or unsubstituted fluorenyl, M is Ge, Si, or Sn, and
- X is Cl, Br, F, or I,
- wherein Z' is an unsubstituted cyclopentadienyl, substituted cyclopentadienyl, unsubstituted indenyl, substituted indenyl, unsubstituted fluorenyl, or a substituted fluorenyl, and wherein substitutents on substituted Z or Z' can be the same or different and are alkyl radicals containing from 1 to 20 carbon atoms.
A compound of the formula Z-MR.sub.2 -Z':
- wherein Z is a substituted or unsubstituted fluorenyl;
- M is Ge or Sn;
- Z' is an unsubstituted cyclopentadienyl, substituted cyclopentadienyl, unsubstituted indenyl, substituted indenyl, unsubstituted fluorenyl, or a substituted fluorenyl;
- and
- wherein each R is an individually selected hydrocarbyl radical and is an alkyl, cycloalkyl, or aryl radical containing 1 or 20 carbon atoms, and wherein substitutents on substituted Z or Z' can be the same or different and are alkyl radical containing from 1 to 20 carbon atoms.
