Twenty-three new volatile trialkyltinderivatives of sulphur containing Schiff bases have been synthesized by the reactions of trimethyltin hydroxide and trialkyltinethoxides with 2,2-disubstituted benzothiazolines. On the basis of molecular weight measurements and infrared proton magnetic resonance spectra, five coordination at tin is proposed for these complexes.

A series of novel sulfonylurea benzothiazolines was designed by splicing active groups and bioisosterism. A solvent-free synthetic route was developed for the sulfonylurea benzothiazoline derivatives via the cyclization and carbamylation. All compounds were characterized by IR, 1H-NMR, 13C-NMR, HRMS. The biological activity tests indicated the compounds could protect maize against the injury caused
