9e were formed (Scheme I). l e gave 88 and 9e on heating the reaction mixture and 8e, 98, and 3e at room temperature. On the other hand, 9f, 6g, 81, and 31 were obtained from l g under hot condition; 2g and 31 were formed when the same reaction was performed at room temperature. l h gave 9h, whereas, at room temperature the reaction products were 2h, 31, in addition to 6h and 9h. I n the case of 11, 81 was the only product. 11 gave 3k, 8k, 81, 91, and 61 when the reaction mixture was heated for 3 h. Authentic samples of 2a, 8b, 6a, 38, 88, 31, 61, 31, 81, and 6h were prepared by the methods reported earlier (3). Experhnental Sectlon

(a) The chalcone dibromkle (la) in Me,SO (20 mL) was heated on a water bath for 3 h and the reaction mixture was allowed to cool to room temperature. I t was diluted with water and the precipitate was fibred off, washed with water, and dried. TLC showed six spots. By column chromatography 8b, 9c, 3b, 6a, and Sa were separated using petroleum ether, benzene, and other as eiuotropic solvents. (b) A mixture of the chalcone dibromide (la) and Me,SO (20 mL) was kept at room temperature for 5 days. I t was then worked up as described above to give 3b, 2a, and 6a. Similarly, the reactions of other chalcone dibromides (lb-1) with Me,SO were carried out and data of the reaction products
