《Ferrocenes Bearing Highly Extended π Systems with Nitrile, Nitro, and Dimethylamino End Groups》 was published in European Journal of Organic Chemistry in 2014. These research results belong to Krausse, Nico; Butenschoen, Holger. Formula: C12H10O2 The article mentions the following:
Oligophenylene-ethynylenes are a popular class of mol. wires for mol. electronics. Replacement of some, not all, of the 1,4-phenylene units by 1,1′-ferrocenylene moieties generates less rigid entities with a limited conformational flexibility. Within this concept, the syntheses of some 1,1′-disubstituted ferrocenes that bear arylethynyl or 4-(arylethynyl)phenyl substituents is presented. In contrast to related compounds with sulfur end groups that were prepared previously, the versions presented here have nitrile end groups, which, according to reported precedence, may serve as points of attachment to gold surfaces. A crystal structure anal. of an unusual diferrocenylethyne derivative is included. In addition, one representative with a push-pull disubstitution that has a nitro and a dimethylamino end group is presented. Many of the prepared compounds have been characterized by cyclic voltammetry.1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6Formula: C12H10O2) was used in this study.
1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6) belongs to ethers.The C-O bonds that comprise simple ethers are strong. They are unreactive toward all but the strongest bases. Although generally of low chemical reactivity, they are more reactive than alkanes. Formula: C12H10O2
