Thiolation of AT-alkenyl compounds with hydrogen sulfide was investigated as a means of obtaining NCCC-SH structures in connection with the synthesis of potential antiradiation drugs. Irradiating allylamine and hydrogen sulfide gave essentially no thiolation. Heating a mixture of allylamine and hydrogen sulfide, with a free-radical-generating agent, gave a mixture, with Markownikoff addition the predominant reaction. With allylamine ...
