This invention relates to new diarylpyrrolecarbonitrile and new diarylnitropyrrole compounds. It also relates to the use of said compounds as insecticidal and acaricidal agents and to a method of protecting plants, particularly crop plants, from attack by insects and acarina by application of a new diarylpyrrolecarbonitrile or diarylnitropyrrole to said plants or to the locus in which they are growing.
developed for the general synthesis of dinitrile-substituted cyclopropanes in moderate to excellent yields. A variety of 2-arylacetonitriles and α-bromoennitriles were compatible under the standard conditions. The reaction was achieved through tandem Michael-type addition followed by intramolecular cyclization. The preliminary application of this method was confirmed by the synthesis of the 2,4-dioxo-3-azabicyclo[3
