Title:
PROCESS FOR PREPARING PENTACENE DERIVATIVES
Document Type and Number:
WIPO Patent Application WO2003027050
Kind Code:
A3
Abstract:
A process for preparing substituted pentacene compounds comprises the step of cyclizing substituted bis(benzyl)phthalic acids using an acid composition comprising trifluoromethanesulfonic acid, the substituted bis(benzyl)phthalic acids being represented by the following general formulas, wherein each R (that is, each of the groups R1 through R8) is independently an electron-donating group, a halogen atom, a hydrogen atom, or a combination thereof.
