ABSTRACT:

This application is a 317 of PCT/EP99/03062 filed May 5, 1999.
The invention relates to novel 2-(2-methylphenyl)-3,4-dihydro-2H-pyrrole derivatives, to a plurality of processes for their preparation and to their use as pesticides.
Hitherto, only few substituted cyclic &agr;,&agr;′-diphenylimines are known: three 2,5-diphenyl-1-pyrrolines which are alkoxy-substituted in the 2-phenyl ring [5-(2,5-dimethoxyphenyl)-2-phenyl-3,4-dihydro-2H-pyrrole and 5-(4-methoxy-phenyl)-2-phenyl-3,4-dihydro-2H-pyrrole from Chem. Ber. 96, 93 (1963) and the corresponding 4-propoxy compound from J. Prakt. Chem., Series 4, 1, 57 (1955)] and the 2,6-diphenyl-3,4,5,6-tetrahydropyridine, which is not substituted any further [cf., for example, Bull. Soc. Chim. Fr. 1974, 258 and Chem. Ber. 116, 3931 (1983)].
Nothing is known concerning their suitability for use as pesticides.
This invention, accordingly, provides novel 2-(2-methylphenyl)-3,4-dihydro-2H-pyrrole derivatives of the formula (I)
