α-Fluorinated cyclic amidophosphite ligands. Their synthesis, Rh complexes and catalytic activity in the hydroformylation of styrene

The synthetic routes to both benzoanellated (3a,b, 5a–e) and monocyclic (8a–c, 9a–c, 14a–g) (amido)phosphate ligands with fluorine containing substituents were elaborated. Their Rh(I) complexes formed in situ demonstrate high activity in the hydroformylation of styrene along with selectivity in respect to branched aldehyde. The “structure–activity” relationship was estimated using quantum-chemical calculations.
