| Abstract: | This paper introduces a new synthetic method for 14-aryl-14H-dibenzoa,j] xanthenes using 2-naphthols and aldehydes as starting materials and polymer-supported sulphonic acid(NKC-9) as a catalyst.The plausible mechanism maybe involves tandem intermolecular dehydration and intramolecular dehydration.This protocol offers advantages of easy operation,mild reaction condition,and good catalyst recovery. |
