Abstract

An efficient strategy for the synthesis of various 2-mercaptobenzothiazole derivatives proceeds from o-haloaniline derivatives and carbon disulfide via a tandem reaction in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) to afford the corresponding 2-mercaptobenzothiazole derivatives in good yields.
