novo synthesis of difluoromethyl pyridines from inexpensive materials is reported. The pyridyl subunit is built around the difluoromethyl group rather than a late stage introduction of this moiety. This user-friendly approach allows access to a diverse range of substitution patterns on all positions on the ringsystem and on the difluoromethyl group.
N-Substituted (6-haloalkylpyridin-3-yl)alkyl sulfoximines are effective at controlling insects.
N-取代(6-卤代烷基吡啶-3-基)烷基磺酰羟胺在控制昆虫方面具有有效性。
