It inhibits the nicotinic acetylcholine receptor and has high potency against sucking pests, including the brown planthopper (Nilaparvata lugens), which has developed serious resistance to conventional neonicotinoids and low cross-resistance to some newly developed neonicotinoids. This review focuses on the discovery, synthesis, structure-activity relationships, and mechanism of action of mesoionic insecticides. Finally, potential directions for the development of mesoionic insecticides are discussed.A versatile one-pot procedure for the preparation of 2-alkyl-substituted N-arylindoles is described. The method combines a visible light-mediated Ni/Ir-photoredox dual catalytic N-arylation of alkynyl anilines under continuous flow conditions with a subsequent base-mediated cyclization to afford the desired substituted indoles. The initial Ni/Ir photoredox-promoted N-arylation of alkynylanilines proceeds efficiently in a continuous flow to afford the desired products in moderate to excellent yields with a short residence time (20 min) and mild conditions at ambient temperature and without the exclusion of air. The methodology was amenable for a multi-gram scale-up to deliver 2-alkyl-N-arylindoles in high yields followed with only a single purification step.The calculation of electron correlation is vital for the description of atomistic phenomena in physics, chemistry, and biology. However, accurate wavefunction-based methods exhibit steep scaling and often sluggish convergence with respect to the basis set at hand. Because of their del
