Bruce, Michael I.; Head, Nicholas J.; White, Allan H.; Skelton, Brian W. published an article on January 31 ,2004. The article was titled 《1,4-Diethynyl-2,5-dimethoxybenzene at ca 150 K》, and you may find the article in Acta Crystallographica, Section C: Crystal Structure Communications.Formula: C12H10O2 The information in the text is summarized as follows:
The principal determinants of packing in crystals of the title compound, C12H10O2, which has crystallog. imposed inversion symmetry, are interactions between the alkyne H atoms and the methoxy O atoms [H···O = 2.39(1) Å]. Crystallog. data are given. In the experiment, the researchers used many compounds, for example, 1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6Formula: C12H10O2)
1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6) belongs to ethers.Formula: C12H10O2Although ethers resist hydrolysis, they are cleaved by hydrobromic acid and hydroiodic acid. Hydrogen chloride cleaves ethers only slowly.
