Document Type and Number:
Japanese Patent JP4955213
Kind Code:
B2
Abstract:
Asymmetric fluorene compounds are formed by reacting an amide starting material; reacting the resultant ketone with a further equivalent of a different organometallic reagent; and a ring closing elimination reaction. Formation of a compound of formula (IV) comprises: (a) reacting a compound of formula (I) with a compound of formula S 1>-M, to give a compound of formula (II); (b) reacting the compound of formula (II) with a compound of formula S 2>-M to give a compound of formula (III); and (c) eliminating H 2X from the compound of formula (III) to give a compound of formula (IV). [Image] [Image] Ar 1>, Ar 2>optionally substituted aryl or heteroaryl groups; X : O, S, NH or NR; L : a bond or a linking group of 1-2 atoms; R, R 1>optionally substituted alkyl, aryl, alkylaryl, arylalkyl or heteroaryl groups; R 2>alkoxy, aryloxy, arylalkyloxy, alkylaryloxy, alkylthio, arylthio, alkylarylthio or arylalkylthio; S 1>, S 2>optionally substituted alkyl, aryl or heteroaryl groups; and M : comprises a metal, and linked to S 1> and S 2> by a carbon-metal bond. Hydrogen is bound to a carbon atom C' of Ar 2>. C' and carbon atom of C=X are separated by 3-5 atoms. An independent claim is also included for new compounds of formulae (V) and (VI). [Image] P : polymerizable group.
