Abstract
A quinone derivative represented by general formula (1) where, in the general formula (1), chemical groups R1 each represent, independently of one another, an alkyl group, a cycloalkyl group, an alkoxy group, an aralkyl group, or an aryl group, and R2 represents an alkyl group, an aralkyl group, a cycloalkyl group, an alkoxy group, an aryl group, or a heterocyclic group.
Claims5
A quinone derivative represented by general formula (1) shown below,
- where, in the general formula (1), chemical groups R1 each represent, independently of one another, an alkyl group having a carbon atom number of no less than 1 and no greater than 10, a cycloalkyl group having a carbon atom number of no less than 3 and no greater than 10, an alkoxy group having a carbon atom number of no less than 1 and no greater than 6, an aralkyl group having a carbon atom number of no less than 6 and no greater than 12, or an optionally substituted aryl group having a carbon atom number of no less than 6 and no greater than 14, and
- R2 represents an alkyl group having a carbon atom number of no less than 1 and no greater than 10, an aralkyl group having a carbon atom number of no less than 6 and no greater than 12, a cycloalkyl group having a carbon atom number of no less than 3 and no greater than 10, an alkoxy group having a carbon atom number of no less than 1 and no greater than 6, an optionally substituted aryl group, or an optionally substituted heterocyclic group.
