Compounds having the formula ##STR1## in which: R is hydrogen, 2-halo, 2-(C.sub.1 -C.sub.4 alkyl), 2-trifluoromethyl, 2-nitro, 2-(C.sub.1 -C.sub.4 alkoxy), 4-halo, 2-halo-6-butynyloxy, or 2,6-dihalo; R.sub.1 is halo, C.sub.1 -C.sub.4 alkyl, trifluoromethyl or cyano, and if R is 2-halo, 2-methyl, 2-nitro, 2-methoxy, 2-trifluoromethyl or 2,6-dihalo then R.sub.1 may also be hydrogen; R.sub.2, R.sub.3, R.sub.4 and R.sub.5 are independently hydrogen or methyl or R.sub.3 and R.sub.4 taken together form a bond; and X is O or S; provided that: a) if R.sub.1 is bromo, R is not 2,6-difluoro; and b) if R.sub.1 is chloro, R is not 2,6-dichloro.
具有以下公式##STR1##的化合物:其中:R为氢,2-卤,2-(C.sub.1 -C.sub.4烷基),2-三氟甲基,2-硝基,2-(C.sub.1 -C.sub.4烷氧基),4-卤,2-卤-6-丁炔氧基,或2,6-二卤;R.sub.1为卤,C.sub.1 -C.sub.4烷基,三氟甲基或氰基,如果R为2-卤,2-甲基,2-硝基,2-甲氧基,2-三氟甲基或2,6-二卤,则R.sub.1也可以是氢;R.sub.2,R.sub.3,R.sub.4和R.sub.5独立地为氢或甲基,或R.sub.3和R.sub.4一起形成键;X为O或S;前提是:a)如果R.sub.1为溴,R不是2,6-二氟;b)如果R.sub.1为氯,R不是2,6-二氯。
