Determination of the products of the reaction of N-alkyl-2-benzothiazolesulfenamide by high-performance liquid chromatography with acetone

A slow reaction was observed between N-alkyl-2-benzothiazolesulfenamide der ivatives and acetone at ambient temperature. The formed products identified by NMR technique are 1,1-bis-(2'-benzothiazolethio)-2-alkylaminoprop-1-ene , 1-(2'-benzothiazolethio)-2-morpholinoprop-1-ene and 2'-(benzothiazolylthi o)propan-2-one. A packed octadecyl-bonded silica column has been employed f or the separation of the main reaction products by HPLC. The precision of t he gradient method used was below 2.3%.
