Aldehyde/ketone-catalyzed highly selective synthesis of 9-monoalkylated fluorenes by dehydrative C-alkylation with primary and secondary alcohols

By using aldehydes or ketones as the catalyst and screening CsOH out as the more effective base than KOH in many instances, an efficient 9-C-alkylation of fluorenes with alcohols was achieved to provide a green and practical method for general synthesis of the useful 9-monoalkylated fluorenes in high selectivities. This new method tolerates a wide range of substrates including activated and unactivated primary and secondary alcohols, thus solving the issues remaining in the field and largely broadening the diversity of the 9-monoalkylated fluorenes. Consequently, fine-tuning of the alkylated fluorenes was made possible to provide specific fluorene monomers for function-oriented polyfluorenes. Preliminary mechanistic studies revealed that the external carbonyl compounds can be quantitatively regenerated and recovered in the reaction cycle.

FULVENE DERIVATIVE AND METHOD FOR PRODUCING FULVENE DERIVATIVE

PROBLEM TO BE SOLVED: To provide a fulvene derivative excellent in characteristics as a luminescent material and a method for producing a fulvene derivative which enables safer production of such a fulvene derivative. SOLUTION: There is provided a fulvene derivative represented by the following formula (1). In the formula, the dotted line arcs may be the same with or different from each other and represent that ring structures are formed together with portions of a five-membered skeleton part; X1 and X2 represent a hydrogen atom or a monovalent substituent which becomes a substituent of a ring structure, where a plurality of them may be bound to respective ring structures which constitute the dotted line arcs; Y1 and Y2 represent one of C, S, N, and O; and R1 and R2 represent atomic groups bound to Y1 and Y2, respectively, and R1 and R2 form a bond at least at one position.
