Carboxy-l -ethenyl)phenyl methyl tellurium was reduced to the corresponding 2-carboxy-1-ethyl derivative by diimide generated from hydrazine and sodium periodate3. [Pg.446]

Carboxy-l -ethyl)-phenyl Methyl Tellurium3 A mixture containing 7 2 g (25 mmol) of 2-(2 -carboxy-l -ethenyl)-phenyl methyl tellurium, 50 g (1 mol) of hydrazine hydrate, 150 m/of DMSO, 2 drops of saturated aqueous copper(II) sulfate solution, and 2 drops of acetic acid is cooled to 0°. This mixture is stirred and a suspension of 30 g (0.14 mol) of sodium periodate in 250 ml of water is added slowly. The mixture is hydrolyzed with acid, the precipitate is filtered off and dissolved in aqueous sodium carbonate solution. Charcoal is added to the solution which is then filtered, acidified, and the precipitate is collected yield 5.8 g (80%) m.p. 105° (from toluene). [Pg.446]

Plants. The primary metabolites are (1-carboxy-l-methyl) allyl 3,5-dichlorophenylcarbamate and Af-(3,5-dichlorophenyl)-2-hydroxy-2-methyl-3-butenamide. Alkaline hydrolysis leads to loss of 3,5-dichloroaniline from vinclozolin and its metabolites. [Pg.1939]

Disposition in the Body. Well absorbed after oral administration. Rapidly metabolised by m- and (m— l)-oxidation of the methyl-propyl side-chain. About 40 to 60% of a dose is slowly excreted in the urine, 5 to 9% as unchanged drug, 30% as 5-(2-carboxy-l-methylethyl)-5-ethylbarbituric acid, 3% as 2 -hydroxysecbuto-barbitone, and 1% as 2 -oxosecbutobarbitone greater amounts of unchanged drug may be excreted after excessive doses.
