The present invention relates to novel compounds and mixtures of geometrical isomers, which are represented by the formula:
wherein
R1 and R2independently of one another are C1-6 alkyl, C1-6 haloalkyl, C3-8 cycloalkyl, C2-6 alkenyl, C2-6 haloalkenyl, C3-6 alkynyl or optionally substituted phenyl; or R1 and R2, together with the nitrogen atom to which they are bonded, form a 5-membered or 6-membered heterocyclic ring which may be benzo-fused or which may be substituted by halogen or C1-4 alkyl; R3 is hydrogen or C1-6 alkyl; R4 is hydrogen or C1-6 alkyl; or R3 and R4, together with the carbon atoms to which they are bonded, form cyclopentylidene or cyclohexylidene; and R5 is C1-6 alkyl, C3-6 alkenyl or benzyl;
further to processes and new intermediates for their production and to their use as herbicides.
There is intended to provide the novel compounds which generate a base easily when irradiated with long wavelength light (active energy rays), a photobase generator containing the compounds and a photobase generation method, and the present invention relates to the compounds represented by the general formula [1], a photobase generator containing the compounds and a photobase generation method:
(wherein, Ar represents any of groups with specific structures selected from the group consisting of an anthracenyl group, an anthraquinonyl group and a pyrenyl group; R

1,4-Disubstituted-5(4H)-tetrazolinones of the formula (I)
(wherein R¹, R² and R³ have the meanings given in the specification), which are known to be useful as herbicides, can be obtained in very good yields by reacting the corresponding 1-substituted-5(4H)-tetrazolinones with the corresponding carbamoyl chlorides in the presence of 4-dimethylaminopyridine.
