Compounds of formula: STR1 in which R1 represents a hydrogen atom or an alkyl, alkoxycarbonyl or an unsubstituted or substituted phenyl radical, R2 represents a hydrogen atom or an unsubstituted or substituted alkyl radical, R3 represents an alkyl, phenylalkyl, indanyl, cycloalkylalkyl or an unsubstituted or substituted phenyl radical, or R2 and R3 form a heterocycle together with the nitrogen atom to which they are attached, and R4 represents an unsubstituted or substituted phenyl radical, a naphthyl, indolyl or quinolyl radical or a phenylamino radical in which the phenyl ring is unsubstituted or substituted, their preparation and medicaments containing them.

The kinetics of the reactions between trimethyloxonium hexafluorophosphate and a series of tetra-n-butylammonium arenesulfonates have been studied in acetonitrile at -23.4 deg C.With the oxonium salt concentration at about 0.01 M, two series of runs were carried out; Hammett plots of the second-order rate coefficients led to ρ values of -1.18 +/- 0.04 for 0.04 M arenesulfonate salt and -1.07 +/- 0.02 for 0.16 M arenesulfonate salt.Solvolysis kinetics for the trimethyloxonium ion in acetonitrile are also reported.
