Efficient synthesis of benzo(hetero)aryl-5-yl(2-hydroxyphenyl)methanones via mechanochemical benzannulation.

A new mechanochemical approach to novel benzo(hetero)aryl-5-yl(2-hydroxyphenyl)methanones is disclosed. The advantages of this approach include its avoidance of potentially harmful organic solvents, relatively short reaction times, and relatively sim…
