The present invention relates to processes for preparing certain 2-pyridones and 2-pyridinols, to novel compounds of these two types and to their use as biologically active compounds, in particular for controlling harmful microorganisms in crop protection, in the medicinal field and in the protection of materials.
The Heck coupling of ArN2BF4 With secondary allylic alcohols, carried out in methanol using Pd(dba)(2) as catalyst without extra ligands and base, leads to the corresponding beta-arylated carbonyl compounds. Such conditions afford arylated acetals from primary allylic alcohols. (c) 2005 Elsevier B.V. All rights reserved.
