In 1992, Crabtree and co-workers reported the first nickel catalyst effective for silane alcoholysis.161 The complex, [Ni(tss)]2 (tss = salicylaldehyde thiosemicarbazone), bears a ligand that contains O and N donor groups and a semicarbazide sulfur. Alcoholysis of Et3SiH with ethanol or methanol occurs at room temperature in 50% dimethyl sulfoxide-benzene. However, the reaction is inhibited in the presence of strong donor ligands, H2, or atmospheric pressure of CO. 

Many solvents are absorbed not only through the respiratory organs but also through the skin e.g. tetrachloromethane, dimethyl sulfoxide, benzene). This leads to dehydration of the skin due to the removal of water and fat, thereby allowing the invasion of bacteria and dirt. 

Solvent. For all practical purposes, NMR spectra are recorded in solution, although pure ( neat ) liquids and even gases can, in principle, also be examined. The solvents must meet certain requirements (Sec. 12.1) and a compromise must often be employed between using concentrated solutions (for high sensitivity) and dilute solutions (for measuring chemical shifts uninfluenced by solute-solute interactions). Besides the commonly used carbon tetrachloride, deuterochloroform, and D2O, a range of deuterated solvents (dimethyl sulfoxide, benzene, pyridine, acetone, dioxane) is commercially available. It must be emphasized that direct comparison of chemical shifts obtained in different solvents is invalid, as solvent-induced changes of up to...

A soln. of excess K-ferf-butoxide in dimethyl sulfoxide added to a soln. of 3 -cholestanyl mesylate in dimethyl sulfoxide-benzene, after 24 hrs. at 25° more K-ferf-butoxide soln. added, and allowed to stand an additional 24 hrs. / -cholestanol. Y 86%.—By this method, equatorial mesylates are efficiently hydrolyzed without inversion. Tosylates give predominantly olefins under the same conditions. F. e. s. F. C. Chang, Tetrah. Let. 196A, 305. 

Stabilized sulfonium ylids. Malononitrile allowed to react overnight with di-cyclohexylcarbodiimide and anhydrous orthophosphoric acid in diethyl sulfoxide-benzene 2-diethylsulfuranylidenemalononitrile. Y 71%. F. e. and limitations s. A. F. Cook and J. G. Moffatt, Am. Soc. 90, 740 (1968).
