New bis:pyrimidinyl-octane derivs. - which are useful as pesticides against leaf insects and ectoparasites

摘要

Nitrogen heterocyclic cpds. of formula (I) and their acid addn. salts are new. In (I) A = alkylene, Het = pyridyl or thiazolyl, both opt substd. Z = alkylene, Y, YA, or YA2Y, Y = cycloalkylene, opt. substd. by alkyl, A1 = alkylene, A12 = a bond O, S, NH alkylene or a gp. (a) pref. A = 2-4C alkylene, Het = pyridyl or thiazolyl both opt substd. by halo, Z = 1-18C alkylene, Y, YA, or YA2Y, Y = 3-7C cycloalkylene opt. substd. by 1-4C alkyl, A1 = 1-4C alkylene, A2 = a bond O, , NH, (a) or 1-4C alkylene. USE - (I) are pesticides which are esp. useful for protection of plants against leaf insects and ectoparasites.
