A simple strategy involving thermal decomposition of the methanesulfonyl radical into the methyl radical and the subsequent transfer of an iodine atom or phenyl telluride group was used to develop a tin-free radical acylation reaction (see scheme; V-40 = 1,1′-azobis(cyclohexane-1-carbonitrile). The key was finding reaction conditions under which the I or PhTe transfer is faster than the direct addition of the alkyl radical to the methanesulfonyl ether.

Approximate rate constants for intermolecular additions of alkyl radicals to phenylsulfonyl oxime ethers (2a and 2b) have been determined to be k(a) = 9.6 x 105 M-1 s-1 at 25°C for 2a and k(a) = 7.3 x 104 M-1 s-1 at 60°C for 2b, indicating that the additions are fast and highly efficient processes. The kinetic data have been confirmed by two competition experiments.

Although acylation represents one of the most useful and thoroughly studied reactions in organic chemistry, a successful free radical mediated acylation is not presently available. free radical carbonylation has recently been reported. This reaction allow
