Herein, we report air-and water-stable borate complexes between scyllo-inositol and aryl boronic acids. The complexes were less reactive than free aryl boronic acids under Suzuki-Miyaura cross-coupling reaction conditions; thus, the borate complexes were used as protected boronic acids. Although protecting groups for organoboronic acids are useful in coupling reactions, especially those used to produce π-conjugated molecules, only a few reports describing the use of protecting groups for boronic acids have been published. The proposed unique structural borate complex provides a novel protective method for aryl boronic acids.

A naphthalene derivative represented by the following formula (1) is provided. In the formula, Ar1 to Ar4 each represent an aromatic hydrocarbon cyclic group having 6 to 18 carbon atoms forming a ring. The aromatic hydrocarbon cyclic group has none of anthracene skeleton, pyrene skeleton, aceanthrylene skeleton and naphthacene skeleton. n, m and 1 each represent an integer in a range of 1 to 5. p represents an integer in a range of o to 5. When n, m, 1 and p each are 2 or more, a plurality of Ar1 to Ar4 may be mutually the same or different.
