The effect of ortho-substitution on the efficacy of biphenyls in mediating electron transfer from lithium was written by Donohoe, Timothy J.;Kershaw, Neil M.;Baron, Ronan;Compton, Richard G.. And the article was included in Tetrahedron in 2009.Product Details of 3929-47-3 This article mentions the following:
A systematic study into the effect of increasing ortho-substitution of a range of biphenyls with respect to their ability to mediate electron transfer from Li metal is described. A synthetic study demonstrated the requirements for effective mediation. The electrochem. reduction of the mediators and of the 2 substrates was studied in THF, 0.1M TBAP, at Pt microelectrodes both at room temperature and at low temperature The formal potentials, E0f extracted from the cyclic voltammograms, are in agreement with results of the synthetic study and computational calculations also provide a correlation. In the experiment, the researchers used many compounds, for example, 3-(3,4-Dimethoxyphenyl)propan-1-ol (cas: 3929-47-3Product Details of 3929-47-3).
3-(3,4-Dimethoxyphenyl)propan-1-ol (cas: 3929-47-3) belongs to ethers. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil. The unique properties of ethers (i.e., that they are strongly polar, with nonbonding electron pairs but no hydroxyl group) enhance the formation and use of many reagents. For example, Grignard reagents cannot form unless an ether is present to share its lone pair of electrons with the magnesium atom. Complexation of the magnesium atom stabilizes the Grignard reagent and helps to keep it in solution.Product Details of 3929-47-3
