Regioselective preparation of pyridin-2-yl ureas from 2-chloropyridines catalyzed by Pd(0)
The palladium-catalyzed ureidation reaction of 2-chloropyridines can be regioselectively performed in good yield, with both aryl and aliphatic ureas, using xantphos as the ligand, Pd(OAc)2 as the source of palladium, NaOt-Bu/H2O or N

Patch preparations for treating plants
The following invention introduces a patch preparation for treating plants, whereas the patch preparations comprise a chemical layer composed of at least one agrochemically active compound, at least one adhesive and optionally, one or more additives. The components are dispersed in a matrix state on a substrate which are then introduced on the roots of the plant to be treated.
