６，１３−ジハロゲン−５，１４−ジヒドロペンタセン誘導体及びそれを用いた６，１３−置換−５，１４−ジヒドロペンタセン誘導体の製造方法

摘要

The present invention provides a 6,13-dihalogen-5,14-dihydropentacene derivative and a method for production thereof. Compounds (b) and (c) are reacted through cross-coupling reaction in the presence of a metal compound and a lithiating agent to synthesize compound (d), which is then halogenated to thereby obtain a 6,13-dihalogen-5,14-dihydropentacene derivative (compound (e)). [wherein X1 and X2 are each a halogen atom, and R1, R2, R3, R4, R5, R6, R7, R8, R9 and R10 are each a hydrogen atom, an optionally substituted C1-C20 hydrocarbon group, etc.]
