[摘要]：[1,2,4]Triazolo[3,4-b][1,3,4] thiadiazines 2a-f and 3,7-dimethyl-4H-[1,2,4] triazino[3,4-b][1,3,4]thiadiazin-6-one 4 were synthesized by one-pot cyclocondensation reaction with alpha-chloroacetonitrile and alpha-haloketones in the presence of catalytic amounts of heteropolyacids in very high yields and rates.
