substituted tropone, 2-mercaptotropone and 2-hydroxytropothione, the former is isolated as a 2:1 complex with 1,1,6,6-tetraphenylhexa-2,4-diyne-1,6-diol, and infrared and electronic absorption spectra of the complex are reported. X-Ray crystal structural study shows that the 2-mercaptotropone in the complex has no bond alternation and then has a delocalized π-electron system.
在 2-巯基取代的托酮、2-巯基托酮和 2-羟基托托酮的两种互变异构体中,前者与 1,1,6,6-四苯基六-2,4-二炔-1,6-二醇形成 2:1 的复合物, 并报道了配合物的红外和电子吸收光谱。X射线晶体结构研究表明,配合物中的2-巯基酮没有键交替,具有离域的π电子体系。
