【Abstract】 This paper discusses cis-trans isomerism in pesticide molecules and associated structure-bioactivity relationships,with emphasis on recent research advances in cis-trans isomer synthesis and its mechanism,including photoisomerism,thermal isomerism,and catalytic isomerism.Also discussed are problems encountered in isomer purification and when studying the mechanism of isomer synthesis.更多还原
