CYCLOHEXENONE DERIVATIVES, PROCESS FOR THEIR PREPARATION AND THEIR APPLICATION AS HERBICIDAL COMPOUNDS

摘要

2-(alpha-oximino-alkyl)- 3-hydroxy-2-cyclohexen-1-one derivs. of formula (I) and their salts are new. (R1 = H or 2-5C alkoxycarbonyl; R2 = 1-4C alkyl; R3 = 1-4C alkyl, 3-4C alkenyl, 3-4C alkynyl, or 3-4C haloalkenyl with 1-3 halogen atoms; R4 = non-aromatic 5-membered ring, opt. contg. a double bond, contg. S, SO or SO2 as a ring-member and opt. substd. by 1-3-1-4C alkyl gps.; n = 0, 1 or 2, n not being O when R4 is a 5-membered ring contg. an SO or SO gp.).
