EFFECTS OF SUBSTITUENTS AND MEDIUM ON ACIDITY OF α,α-BIS(BUTYLSULFONYL)TOLUENES

Article abstract of DOI:10.1135/cccc19940391

Seven substituted α,α-bis(butylsulfonyl)toluenes and three 2-aryl-1,1,3,3-tetraoxo-1,3-dithiolanes have been prepared and their 1H NMR, IR, and MS spectra measured.The pK_HA values of the substituted α,α-bis(butylsulfonyl)toluenes have been determined by potentiometric titration in dimethyl sulfoxide, dimethylformamide, and 80percent (v/v) mixture of dimethyl sulfoxide and water.The results are intterpreted by the Yukawa-Tsuno relationship (parameter r = 0.43 - 0.49) and classified in relation to analogous N- and O-acids by the methods with latent variables (the method of conjigated deviations).
