| 4 | Description | Abstract | An efficient and convenient methodology is introduced for preparation of xanthones and dixanthones through direct coupling of salicylic acids and phenols. It is based on the use of POCl3 and catalytic amount of calix[4]arene sulfonic acid as a highly thermally stable and recyclable organocatalyst. A variety of salicylic acids and phenols were treated with POCl3 and the catalyst in the absence of solvent at 80 oC which afforded the corresponding xanthones in good to high yields. |
