Popis: We have photolyzed potassium dimesityldiphenylborate in 1,2-dimethoxy ethane/water solution with light in the region of 2537 A in the presence of air. The products were phenol (VI), 2-hydroxymesitylene (VII), 2,4,6-trimethylbiphenyl (VIII), and (2,4,6-trimethyl-3-biphenylyl)mesitylphenylborane (XI). The structure of XI was determined from spectroscopic data, chemical degradation, and synthesis. We believe the presence of XI as a photoproduct is evidence for the original generation of a phenyl radical and a dimesitylphenylborane radical anion by photolysis of the borate salt. We have proposed reaction sequences to account for the reaction products, based on an intramolecular attack by radical species.
