摘要

Substituted aminoketals of the formula (I) IMAGE in which Thi, A, m, R1 and R2 have the meanings given in the text, and their use as pesticides. The novel substituted aminoketals of the formula (I) can be obtained, for example, when suitable dioxolanes are reacted with suitable amines or suitable dioxolanes substituted by a thienylalkenyl radical are hydrogenated. Furthermore, dioxolanes of the formula (II) IMAGE in which Thi, A, m and Y have the meaning given in the description and suitable processes for their preparation, for example from suitable ketones by reaction with suitable diols.
