Dimethyl telluride, (CH3)2Te.—The method first used for isolating this substance consisted in treating a potassium-tellurium alloy with a concentrated aqueous solution of barium methyl sulphate.1 It appears doubtful whether the method can actually be used for obtaining dimethyl telluride itself, although it might be used for derivatives of this body. An excellent yield of dimethyl telluride is obtained according to the equation 2... 

When methyl 4,6-benzylidene-2-desoxy-a-D-galactoside (LXXXVI)126 was treated with phosphorus oxychloride in pyridine at —40°, followed by barium hydroxide,236 it gave amorphous barium methyl 4,6-benzyli-dene-2-desoxy-a-D-galactoside 3-phosphate (LXXXVII). If diphenyl-phosphoryl chloride [diphenylchlorophosphonate, (PhO)2POCl]236 240 in pyridine was used as the phosphorylating agent, then crystalline (methyl...

To study the dependence of the reaction rates on the constitution and configuration of the ozonides, an automatic method was worked out. Ozonides, dissolved in absolute methanol which was saturated with the barium salt of the acid produced in the reaction (mainly barium acetate or barium benzoate), were heated in a thermostat to 50°C. In a Combi-titrator (Methrom Co.) a methanol solution of barium methylate (0.1 N) was added automatically at such speed that the pH of the solution remained unchanged. The variation in the volume of added methylate solution with reaction time was registered on chart paper. The reactions were carried out under pure nitrogen, and the curves always showed first-order kinetics.
