The synthesis and crystal structure of 1,7-bis(4-methoxyphenyl)-4-(1,3-dithiolan-2-ylidene)-1,6-heptadiene-3,5-dione is described. This compound crystallizes in the space group P21 with unit cell parameters a = 14.207 Å, b = 7.752(1) Å, c = 19.473(1) Å, β = 91.00(3)°, with two molecules in the asymmetric unit. The ketenedithioacetal functionality present between the carbonyl groups prevents the possibility of keto-enol tautomerization in this compound. The cinnamoyl groups are organized parallel to each other due to the push–pull nature of the ketenedithioacetal functionality. The details regarding the synthesis and crystal structure of the title compound are reported in this paper.
介绍了 1,7-双(4-甲氧基苯基)-4-(1,3-二硫环戊-2-亚基)-1,6-庚二烯-3,5-二酮的合成和晶体结构。该化合物在空间群 P21 中结晶,单胞参数 a = 14.207 Å, b = 7.752(1) Å, c = 19.473(1) Å, β = 91.00(3)°, 不对称单元中有两个分子。羰基之间的二硫代酮缩醛官能团阻止了酮烯醇在该化合物中发生同分异构的可能性。由于二硫代二乙醛官能团的推拉性质,肉桂酰基彼此平行排列。本文报告了标题化合物的合成和晶体结构细节。
