Summary:Compounds of formula: in which R4 is a hydrogenolysable group, R and R1 are alkyl groups, X<-> is an HSO4<->, Cl<-> or R7SO3<-> anion. The invention also relates to a process for preparing the compounds of formula (I) by hydrolysis of compounds of formula (II) in which R2 and R3 are alkyl groups bonded to oxygen via a secondary carbon by means of sulphuric or hydrochloric acid. The invention also relates to the use of the compounds of formula (I) for the preparation of a herbicide by hydrogenolysis of the compounds of formula (I)
