Abstract
A novel compound useful as a raw material for a resist material is described. A norbornene derivative having epoxy and a methylene-mediated reactive group in a norbornane skeleton is represented by the following formula. In the formula, R1 represents a hydrogen atom, acryloyl, methacryloyl or hydroxymethylacryloyl, and R2 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.
Claims6
A norbornene derivative represented by formula (I),
- wherein R1 represents a hydrogen atom, acryloyl, methacryloyl or hydroxymethylacryloyl, and R2 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms.
A method for producing a norbornene derivative, comprising:
- a) a Diels-Alder reaction step of reacting cyclopentadiene with a compound of formula (A) to obtain a norbornene derivative (B);
- b) a reduction step of reducing the norbornene derivative (B) to obtain a norbornene-methylol derivative (C) represented by formula (C);
- c) an esterification step of esterifying the hydroxyl group of the norbornene-methylol derivative (C);
- and
- d) an epoxidation step of oxidizing the unsaturated bond of the norbornene skeleton of the norbornene-methylol derivative (C),
- wherein step a) and step b) are followed by either step c) or step (d), and the norbornene derivative is represented by formula (E),
- wherein in formule (A), (B), (C) and (E), R2 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, and R3 represents acryloyl, methacryloyl or hydroxymethylacryloyl.
