2-Substituted 3-chlorobenzaldehydes were prepared from the corresponding 2-(3-chlorophenyl)-1,3-dioxolanes using an ortho-lithiation strategy. The 6-chloro-2-formylbenzamide exists only in a ring form, but 6-chloro-2-formylbenzoic acid esters were isolated in both forms as open chain and cyclic tautomers. 7-Chloro-3-hydroxy-3H-isobenzofuran-1-one reacted with nucleophilic reagents at the carbonyl or quaternary carbon depending on the character of nucleophile.

‐Heterocycle‐Substituted Iodoarenes (NHIAs) to Efficient Organocatalysts in Iodine(I/III)‐Mediated Oxidative Transformations

The reactivity of ortho‐functionalized N‐heterocycle‐substituted iodoarenes (NHIAs) as organocatalysts in iodine(I/III)‐mediated oxidations was systematically investigated in the α‐tosyloxylation of ketones as the model reaction. During a systematic catalyst evolution, it was found that NH‐triazoles and benzoxazoles have the most significant positive influence on the reactivity of the central iodine
