Abstract

An expedient two‐step synthesis of [^13^C~2~]DMSO, starting from commercially available [^13^C]methyl iodide, is described. The product obtained in 57% yield is of high chemical (≥ 99%) and isotopic purity (= 98% ^13^C~2~, 2% ^13^C~1~), as jugded by NMR‐spectroscopy and a GC‐MS‐assay.

## Abstract Trimethyloxosulfonium‐^13^C iodide (30% ^13^C‐enriched) was prepared from ^13^C‐labelled barium carbonate by proceeding through methanol‐^13^C and methyl‐^13^C iodide. The original procedure for the preparation of trimethyloxosulfonium iodide which afforded 53.6% of product was modified

## Abstract An efficient route is described for the preparation of [^13^C~6~]‐ϵ‐caprolactam (**1b**), and thence to [^13^C~6~]‐hexamethyleneimine (**2b**) hydrochloride. The sequence, from [^13^C~6~]‐phenol, uses a rhodium‐catalysed hydrogenation to generate labelled cyclohexanol, and thence cycloh
