Dhr. Barton et al., THE REACTION OF CARBON RADICALS WITH SULFUR - A CONVENIENT SYNTHESIS OF THIOLS FROM CARBOXYLIC-ACIDS, Tetrahedron letters, 35(33), 1994, pp. 6057-6060
A new synthesis of thiols in high yield utilizing carbon radicals and
elemental sulfur is demonstrated. The procedure is applicable to 1 deg
rees, 2 degrees and 3 degrees carboxylic acids.
