Abstract:
    The invention relates to compounds of formula in which R4 is a group which can be hydrogenolyzed, R and R1 are alkyl groups, X- is an HSO4-, Cl- or R7SO3- anion and to a process for the preparation of the compounds of formula (I) by the hydrolysis of the compounds of formula (II) in which R2 and R3 are alkyl groups linked to the oxygen via a secondary carbon, using sulphuric or hydrochloric acid. The invention also relates to the use of compounds of formula (I) for the preparation of herbicide by the hydrogenolysis of the compounds of formula (I).
