(Di)benzoxanthones possessing additional benzene units on one or both sides of xanthone were prepared via dehydration of the corresponding dihydroxybenzophenone, where a catalytic amount of K2CO3 dramatically increased the yields. Chemical transformations of the versatile carbonyl groups of (di) benzoxanthones could derive fluorescent materials. (C) 2012 Elsevier Ltd. All rights reserved.
