Reactions of 1,4-diethenylbenzene derivatives with Ru(H)(Cl)(CO)(PPh3)2 followed by PMe3 to give binuclear Ru divinylbenzene complexes [RuCl(CO)(PMe3)3]2(μ-CH:CH-Ar-CH:CH) (Ar = C6H4 (6a), C6H3CH3 (6b), C6H3OCH3 (6c), C6H3F (6d), C6H3Cl (6e), C6H3Br (6f), C6H3CN (6g), C6H3NO2 (6h), C6H2Me2-2,5 (6i), C6H2(OCH3)2-2,5 (6j), C6H2(F)2-2,5 (6k), C6H2(CF3)2-2,5 (6l), and C6H3CF3 (6m)). The resp. products were characterized by elemental analyses, NMR spectrometry, and UV/visible spectrophotometry. The structures of 6h, 6i, and 6j were established by x-ray crystallog. Electrochem. studies revealed that intermetallic electron communication between the two Ru centers may be fine-tuned by modification of the bridging spacers, i.e., by introducing one or two substituent groups on the 1,4-diethenylphenylene bridge. Electron-releasing substituents facilitate electron communication between the two metal centers. In the experiment, the researchers used many compounds, for example, 1,4-Diethynyl-2,5-dimethoxybenzene(cas: 74029-40-6Application In Synthesis of 1,4-Diethynyl-2,5-dimethoxybenzene)
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. Application In Synthesis of 1,4-Diethynyl-2,5-dimethoxybenzene
