Solvent effect in michaelis-becker reaction
In the systems: dialkyl phosphite (dialkyl thiophosphite)-alkyl thiocyanate-alkaline agent the unambiguous transformations via the Michaelis-Becker reactions proceed under the conditions of ion-dipole reactions with involvement of the unsolvated dialkyl phosphite or dialkyl thiophosphite anions. Sodium methylate, ammonia, and the alkali metal hydroxides can be used to form the latter in the presence of either dimethylformamide or hexamethylphosphoric triamide.
