Aryl nitriles were efficiently synthesized through copper-mediated cyanation of aryl halides using benzyl cyanide as the cyanide source. Aryl halides with various substituents on the aromatic ring afforded the corresponding aryl nitriles in 32–97 % yields (25 examples). This reaction could also be carried on a gram scale by using commercially available reagents. Additionally, a C–H bond oxidation and

2-Iodylphenol ethers were prepared by the dimethyldioxirane oxidation of the corresponding 2-iodophenol ethers and isolated as chemically stable, microcrystalline products. Single-crystal X-ray diffraction analysis of 1-iodyl-2-isopropoxybenzene 8c and 1-iodyl-2-butoxybenzene 8d revealed pseudopolymeric arrangements in the solid state formed by intermolecular interactions between IO2 groups of different
The first enantioselective intramolecularC−Hinsertion and cyclopropanation reactions of donor‐ and donor/donor‐carbenes by a nondiazo approach are reported. The reactions were conducted in a one‐pot manner without slow addition and provided the desired dihydroindole, dihydrobenzofuran, tetrahydrofuran, and tetrahydropyrrole derivatives with up to 99 % ee and 100 % atom efficiency.

The preparation, X-ray structure, and reactivity of new, highly soluble, and reactive iodonium ylides derived from malonate methyl ester and bearing an ortho substituent on the phenyl ring are reported. These new reagents show higher reactivity than common phenyliodonium ylides in the Rh-catalyzed cyclopropanation, C–H insertion, and transylidation reactions under homogeneous conditions.
