(4-甲基-1,3-二噻烷-2-亚甲基)-1,7-二芳基-1,6-二烯-3,5-二酮的合成

Synthesis of 4-(4-methyl-1,3-dithiol-2-ylidene)-1,7-diaryl-1,6-diene-3,5-dione

从2,4-戊二酮和1,2,3-三溴丙烷出发合成了一类新的α-羰基二硫缩烯酮类化合物,并以其为底物合成了(4-甲基-1,3-二噻烷-2-亚甲基)-1,7-二芳基-1,6-二烯-3,5-二酮类化合物,通过IR和1H NMR方法对其进行了表征.

3-（4-（bromomethyl）-1, 3-dithiolan-2-ylidene） pentane-2,4-dione was synthesized from pentane-2,4-dione, it＇s reactions such as condensation with arylaldchydes were investigated, 3-（4-methyl- 1,3-dithiol-2-ylidene） pentane-2,4-dione and 4-（4-methyl-1,3-dithiol-2-ylidene）-1, 7-diaryl-1,6-diene- 3,5-dione were obtained. All compounds were characterized by IR and ^1H NMR spectra.
