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 Ar

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 organoboronicacids are useful in coupling reactions, especially those used to produce
