2-(2,6-difluorophenyl)-4-(2-ethoxy-4-tert-butylphenyl)-2-oxazoline

2-Substituted phenyl-2-oxazoline derivatives or 2-substituted phenyl-2-thiazoline derivatives represented by the general formula (I) ##STR1## in which R.sub.1 and R.sub.2 may be same or different and each represents a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group, a nitro group, a lower haloalkyl group or a lower haloalkoxy group, with a proviso that R.sub.1 and R.sub.2 do not simultaneously represent hydrogen atoms;

2-Substituted phenyl-2-oxazoline or thiazoline derivatives, process for

A compound represented by the following formula ##STR1## wherein X.sup.1 and X.sup.2 are identical or different and each represents a hydrogen atom, a lower alkyl group, a lower alkoxy group, a halogen atom, a trifluoromethyl group or a trifluoromethoxy group;

Oxa- or thia-zoline derivative

A compound of the formula ##STR1## wherein Y represents a halogen atom, a lower alkyl group, a lower alkoxy group or a trifluoromethyl group and R represents a lower alkyl group. This compound can be produced by reacting a compound of the formula ##STR2## or a reactive derivative thereof with an aniline derivative of the formula ##STR3## and is useful as a herbicide.

Phenylacetanilide derivatives

A compound of the general formula ##STR1## wherein X.sub.1 represents a hydrogen, fluorine, chlorine or bromine atom, X.sub.2 represents a fluorine, chlorine or bromine atom, R represents a hydrogen atom or a lower alkyl group, and Y represents a fluorine, chlorine or bromine atom, or a trifluoromethyl or cyano group. This compound is prepared by reacting a compound of the formula ##STR2## or a reactive derivative thereof with a compound of the formula ##STR3## and is useful as an insecticide.

Alpha,alpha-dimethylphenylacetanilide derivatives, process for

A herbicidal composition containing as an active ingredient a compound of the formula ##STR1## wherein R.sub.0 represents a hydrogen atom or a lower alkyl group, and R.sub.1, R.sub.2 and R.sub.3 each represent a hydrogen or halogen atom, or a lower alkyl, lower alkoxy or lower alkenyloxy group, which is especially useful for application to aquatic rice paddies, and novel compounds of formula (I) wherein R.sub.0, R.sub.1, R.sub.2 and R.sub.3 have the same meanings as defined above, provided that R.sub.1, R.sub.2 and R.sub.3 do not represent hydrogen atom at the same time.
