with aliphatic hydrocarbon radicals substituted by carbon atoms having three bonds to hetero atoms with at the most one bond to halogen, e.g. ester or nitrile radicals, directly attached to ring carbon atoms, said aliphatic radicals being substituted in the alpha-position to the ring by a hetero atom, e.g. [IMAGE cpc-sch-C07D-1029.gif] with m >= 0, Z being a singly or a doubly bound hetero atom
