Rhodium-catalyzed C-H insertions and cyclopropanations of donor/acceptor carbenes have been used for the synthesis of positional analogues of methylphenidate. The site selectivity is controlled by the catalyst and the amine protecting group. C-H functionalization of N-Boc-piperidine using Rh2 (R-TCPTAD)4 , or N-brosyl-piperidine using Rh2 (R-TPPTTL)4 generated 2-substitited analogues. In contrast,
Using a simple copper(I) catalyst has allowed a high yielding sulfonylative-Suzuki–Miyaura cross-coupling reaction to be developed. The process provides a single step route to diaryl sulfones from the direct combination of aryl boronic acids, sulfur dioxide and aryl iodides, and represents the first sulfonylative variant of a classic cross-coupling reaction. Sulfur dioxide is delivered from the surrogate

A practical and straightforward bimetallic Pd/Cu catalytic system has been developed. This system affords various sulfonamides in onepotfrom easy‐to‐handle and readily available boronic acids, sulfur dioxide surrogate DABSO and O‐benzoyl hydroxylamines in high yields. Without additional ligands, the newly developed catalytic system revealed a broad substrate scope for both partners and tolerated
