Abstract
A novel vinyl-group-containing fluorene compound and a method for producing the same, a polymerizable monomer and cross-linking agent including this compound, a leaving-group-containing fluorene compound, a monovinyl-group-containing fluorene compound, and methods for producing the same. This vinyl-group-containing fluorene compound is represented by formula (1). In the formula, Wand Wrepresent a group represented by formula (2), a group represented by formula (4), a hydroxyl group, or a (meth)acryloyloxy group, Rand Rrepresent a cyano group, a halogen atom, or a monovalent hydrocarbon, and n1 and n2 are integers of 0-4. In formulas (2) and (4), a ring (Z) is an aromatic hydrocarbon ring, X is a single bond or a group represented by —S—, Ris a single bond or a C1-4 alkylene group, Ris a specific substituent group such as a monovalent hydrocarbon, and m is an integer of 0 or greater.
