Abstract
Sodium derivatives of 2-hydroxy-phenones react with RuHClCO(PPh3)3 and with the dimer [RuClCO(CH3CHCN)(PPh3)2]2 in THF at ambient temverature to give chelated phenone derivatives of the tyDe RuH(Phen)CO(PPh3)2 and Ru(Phen)(CH3CHCN)CO(PPh3)2. The ligands used in this study are 2-hydroxyacetonhenone. 2-hydroxy-4,6-dimethoxy-acetophenone, 2-hydroxypropionophenone. 2-hydroxy-benzophenone and 2-hydroxy-4-methoxybenzophenone. Stereochemical assignments have been made on the basis of IR an3 1H NMR data.
