N-(Pyrid-3-yl)thioureas and Derivatives as Acaricides. I. Synthesis and Biological Properties

Pascual, Alfons,Rindlisbacher, Alfred

, p. 253 - 264 (2007/10/03)

In the course of optimization studies around diafenthiuron, the central aromatic nucleus linked directly to the thiourea unit was replaced by a pyridine moiety. A series of N-(pyrid-3-yl)thioureas, isothioureas and -carbodiimides was synthesised and evaluated for acaricidal activity. The synthetic methodology used and the screening results against some spider mites (Tetranychus spp. and Panonychus ssp.) are discussed.
