An efficient, chemoselective homologation of disulfides and diselenides to the corresponding dithio- and diselenoacetals has been developed via the addition of bromomethyllithium. Chemoselectivity is fully preserved in the presence of...

A laboratory test method for assessing the activity of chemicals against the eggs and young mites of the glasshouseredspider (Tetranychus telarius L.) is described. The results given by a series of SS′-disubstituted alkane-αω-dithiols using this test method are tabulated and discussed.

A novel and convenient synthetic route towards new bis-benzimidazoles, -benzothiazoles and -benzoxazoles from readily available starting materials has been established. These compounds have thioethers at the 2 position of the heterocycle and the resultant carbon–thioether linkage is stable under the conditions of synthesis. The crystal structures of bis(benzoxazol-2-ylsulfanyl)methane, bis(benzoth
