摘要

1-(Alkyl/arylthiocarbamoyl) benzotriazoles 4a-i were synthesized in yields of 91-99% from bis (benzotriazolyl) methanethione (3). Reagents 4a-g were then used as isothiocyanate equivalents for the efficient synthesis of 10 secondary and 14 tertiary thioureas in high- yielding, convenient processes.
