Abstract
Provided is a fluorene compound having a sulfonic acid ester structure and an allyl group, the compound being represented by formula (1). (In the formula, R1 each independently are a hydrogen atom or a methyl group. R2 each independently are a C1-20 hydrocarbyl group, some or all of the hydrogen atoms of which may be substituted by a halogen atom, a nitro group, or a cyano group, and an ester bond or an ether bond may be present between the carbon-carbon bonds thereof.)
Claims5
A fluorene compound having sulfonic acid ester structures and allyl groups, represented by the formula (1):
- wherein R1 is each independently hydrogen or methyl and
- R2 is each independently a C1-C20 hydrocarbyl group in which some or all of the hydrogen atoms may be substituted by halogen, nitro or cyano, and an ester bond or ether bond may intervene in a carbon-carbon bond.
A method for preparing a fluorene compound represented by the formula (1), comprising the step of reacting a fluorene compound having allyl groups, represented by the formula (2), with a compound represented by the formula (3) or (4),
- wherein R1 is each independently hydrogen or methyl,
- wherein R2 is each independently a C1-C20 hydrocarbyl group in which some or all of the hydrogen atoms may be substituted by halogen, nitro or cyano, and an ester bond or ether bond may intervene in a carbon-carbon bond, and X is fluorine, chlorine or bromine,
- wherein R1 and R2 are as defined above.
