NOVEL HETEROCYCLES BASED ON 1, 3, 4-THIADIAZOLE SCAFFOLD AS INSECTICIDES [PDF]
Journal of Environmental Science, 2017 The crop plants are the major source of human nutrition, but insects and pests cause huge economic losses every year. The authors were interested in developing novel insecticidal agents with low toxicity and an acceptable impact on the environment. Thus, 2-amino-5-(substituted)-1, 3, 4-thiadiazoles (1a, b) were used as versatile materials to synthesize
