Title:

DIBENZO [g,p] CHRYSENE DERIVATIVE, AND METHOD FOR PRODUCING THE SAME

Document Type and Number:

Japanese Patent JP2023070620

Kind Code:

A

Abstract:

To provide a dibenzo [g,p] chrysene derivative having horizontally asymmetrical substituent to a central naphthalene ring, and a method for producing the derivative, especially a dibenzo [g,p] chrysene derivative having a same first substituent at position 3 and position 14, and having a same second substituent different from the first substituent at position 6 and position 11, and a method for producing the derivative.SOLUTION: There is provided, a dibenzo [g,p] chrysene derivative having a same first substituent at position 3 and position 14, and having a same second substituent different from the first substituent at position 6 and position 11. A method for producing the dibenzo [g,p] chrysene derivative includes: (a) a process of dimerizing fluorenone derivative having the same first substituent at positions 2, 7, and fluorenone derivative having the same second substituent different from the first substituent at positions 2, 7, and producing a spiro ketone derivative; (b) a process of reducing a carbonyl group of the obtained spiro ketone derivative, and manufacturing a spiro alcohol derivative having a hydroxyl group; and (c) a process of dehydrating the obtained spiro alcohol derivative, and obtaining a dibenzo [g,p] chrysene derivative.SELECTED DRAWING: None
