Abstract

The aliphatic and alicyclic esters of N-hydroxypyridine-2-thione are readily reduced by tributylstannane in a radical chain reaction to furnish nor-alkanes. 1 In the absence of the stannane a smooth decarboxylatlive rearrangement occurs to give 2-substituted thiopyridines. 1 The radicals present in this reaction provoke with t-butylthiol an efficient radical reaction with formation of nor-alkane and 2-pyridyl-t-butyl disulphide. 1Similarly ...
