ABSTRACT This invention relates to novel compounds of formula [I], a process for their production, and their use as a herbicide: Image ..... [I] wherein A represents the bond -N= or -?= in which X is a hydrogen atom, a chlorine atom, a nitro group or a trifluoromethyl group; B represents a hydrogen atom, a methyl group or a methoxy group; and Ar represents one member selected from the group consisting of Image , Image , Image , Image , Image , Image , Image , Image , Image , Image and Image in which R1 to R38, independently from each other, represent a hydrogen atom, a lower alkyl group or a lower alkoxy group; R16 may further represent a hydroxyl group; a pair of R2 and R3, a pair of R6 and R7 and a pair of R9 and R10 each, taken together, may represent an alkylene linkage and may form a 5- or 6-membered ring together with the two adjacent carbon atoms to which they are bonded; R11 and R12, taken together, may form an ethylene- dioxy linkage O-(CH2)2-O-, or R11 and R15, taken together, may form an alkylene linkage and form a 5- or 6-membered ring together with the carbon atoms to which they are bonded, or R15 and R15, taken together, may represent a methylene linkage and form a 5- or 6-membered ring together with one carbon atom to which they are bonded, or R14 and R15, taken together, may form a dichloro- methylene linkage. A small group of compound of formula [I] are excluded. They are those wherein A is -?= in which X is hydrogen, chlorine, nitro or trifluoromethyl; B is methyl or methoxy; and Ar is Image (in which R1 and R2 are each hydrogen and R3 and R4 are each methyl), Image (in which R7 and R8 are hydrogen and R5 and R6 are methyl) or Image (in which R23 and R24 are each hydrogen and R25 and R26 are each methyl).
