- AMINOMETHYLATION OF THIOUREA DERIVATIVES WITH N-METHYLENE-tert-BUTYLAMINE. I. N-MONOSUBSTITUTED THIOUREAS
-
Reactions of N-monosubstituted thioureas with N-methylene-tert-butylamine proceed by a reaction of the Mannich type via a key azacarbenium ion with formation of 1-R-5-tert-butyl-3,4,5,6-tetrahydro-1,3,5-triazine-2-thiones in quantitative yields.A similar reaction with unsubstituted thiourea gives complete aminomethylation to 2-(N-tert-butylaminomethyl)mercapto-5-tert-butyl-3,4,5,6-tetrahydro-1,3,5-triazine.
