Catalysis of a free radical allylic displacement by allyl iodide

الملخص EN

The preparation of ally chlorostannan 5 was achieved into two steps via free radical displacement of the sulphone group by tributyltin radical.

The chemical structure of compound 5 was confirmed by normal spectroscopic methods, including NMR, IR and MS.

The mechanism for the free radical reaction of chlorosulphone 6 with tributyltinhydride is likely to proceed via the catalysis of the trace amount of the ideally chloride 4.
