摘　　要：An eco-friendly and practical method for the clean preparation of 5-amino-1,2,4-thiadiazoles was devel-oped.With WS_(2)as the semiconductor photocatalyst,both TEMPO and O_(2)(in air)as the redox catalysts,a variety of thiadiazoles were semi-heterogeneously formed in high to quantitative yields and could be easily collected by CPME extraction and rinsing.Furthermore,the catalytic system can be reusable for at least 5 reaction runs.
