Process for the sulphinylation of heterocyclic cpds. comprises reaction of a deriv. of formula RS(O)X with a heterocyclic cpd. Het. R = 1-4C alkyl (opt. substd. by one or more halo); X = halo, hydroxy(or one of its salts), -NR2R3 or aryloxy; R2, R3 = 1-4C alkyl or haloalkyl; aryl = pref. phenyl (opt. substd. by one or more halo or 1-4C alkyl or haloalkyl); Het = a pyrrole, pyrazole, imidazole, oxazole, iso-oxazole, isothiazole, thiazole or triazole (all opt. substd. by one or more halo, amino, mono- or di-alkylamino, nitrile or aryl (opt. substd. by one or more halo and/or one or more alkyl, haloalkyl or SF5); provided that R is not n-butyl when Het = pyrrole and R is not methyl when Het = 2,5-dimethyl pyrrole. Intermediates RS(O)NH-Het are new. |
