Chiral Ru/PNNP complexes in catalytic and stoichiometric electrophilic O- and F-atom transfer to 1,3-dicarbonyl compounds
Abstract:
The asymmetric hydroxylation and fluorination catalyst [Ru(OEt2)2(PNNP)]2+ (PNNP = chiral tetradentate ligand with a P2N2 donor set) reacts with 1,3-dicarbonyl compounds to give dicationic adducts and, upon deprotonation, the corresponding enolato complexes. The relevance of these species to catalytic O- and F-transfer is investigated.
