Abstract
A study of benzylic sulfonates and their corresponding N-methylsulphon amide derivatives as substrates in potential free radical [1,6] ipso s ubstitution reactions reveals a preference for the alternative [1,7] a ddition mode. Empirical guidelines for biaryl and heterobiaryl synthes is using this approach can then be made. Copyright (C) 1996 Elsevier S cience Ltd
