Diethyl methyl carbinol

Syntheses with methoxymethyllithium. A soln. of monochloromethyl ether in methylal added gradually with stirring to a suspension of powdered Li in methylal at —25 to —30° after the reaction has been started at 0°, then allowed to react with diethyl ketone diethyl(methoxymethyl)carbinol. Y 75%. F. e. s. U. Schollkopf and H. Kiippers, Tetrah. Let. 1964, 1503 Grignard syntheses with 1,1-alkoxyhalides in methylal s. E. Taeger, E. Kahlert, and H. Walter, J. pr. 28,13 (1965). 

Anhydrous stannous chloride, a water-soluble white soHd, is the most economical source of stannous tin and is especially important in redox and plating reactions. Preparation of the anhydrous salt may be by direct reaction of chlorine and molten tin, heating tin in hydrogen chloride gas, or reducing stannic chloride solution with tin metal, followed by dehydration. It is soluble in a number of organic solvents (g/100 g solvent at 23°C) acetone 42.7, ethyl alcohol 54.4, methyl isobutyl carbinol 10.45, isopropyl alcohol 9.61, methyl ethyl ketone 9.43 isoamyl acetate 3.76, diethyl ether 0.49, and mineral spirits 0.03 it is insoluble in petroleum naphtha and xylene (2).

A similar substituent effect operates in the reaction of indole with diethyl ketomalonate conducted by microwave irradiation oti montmorillonite K-10 clay [125]. Indole, its 1-methyl and 2-methyl derivatives, along with C-ring analogs, gave mixtures of both the 3-carbinol and te-indol-3-yl products.

Some new reactions involving intermolecular reactions of fluoroaryl-substituted stabilized carbanions are summarized in Schemes 7—10. Studies on monosubstituted diethyl malonates have shown that the effect of a penta-fluorophenyl group on the acidity of the C—bond in this system is comparable to the effect of a 2- or 4-nitrophenyl group. Tris(polyfluoroaryl)methyl radicals have also (c/. Scheme 10) been generated by treatment with chromium(n) perchlorate of the corresponding cations generated from tris(polyfluoroaryl)carbinols and trifluoroacetic acid. ...
