TETRAZOLES. XVI. ALKYLATION OF TETRAZOLES UNDER THE CONDITIONS OF PHASE-TRANSFER CATALYSIS

The alkylation of tetrazole and 5-substituted tetrazoles with dimethyl sulfate and methyl iodide in the two-phase methylene chloride-water system in the presence of tetrabutylammonium bromide was investigated.The alkylation of tetrazoles with methyl iodide takes place in the organic phase, while that with dimethyl sulfate takes place both in the organic and in the aqueous phases.The ratio of the isomeric tetrazoles formed during the alkylation of 5-aryltetrazoles by methyl iodide correlate with the substituent constants ?.The use of phase-transfer catalysis during the alkylation of tetrazoles does not lead to a change in the selectivity of the reaction.

TETRAZOLES. VIII. KINETICS AND RATIO OF THE REACTION PRODUCTS IN THE ALKYLATION OF THE SALTS OF SUBSTITUTED 5-PHENYLTETRAZOLES BY DIMETHYL SULFATE IN ACETONITRILE

The kinetics and the ratio of the reaction products were investigated for the alkylation of potassium salts of a series of substituted 5-phenyltetrazoles by dimethyl sulfate in acetonitrile.It was shown that with the salt at a concentration of less than 10-3M the corresponding tetrazolate ion enters into reaction with dimethyl sulfate.Electron-withdrawing substituents in the benzene ring reduce the rate of the alkylation reaction and help to increase the proportion of the N2 isomer in the reaction products.The rate constants for the reaction of substituted 5-phenyltetrazoles with dimethyl sulfate and the ratios of the isomeric tetrazoles formed during alkylation correlate with the ? constants of the substituents.
