Abstract
Previously unknown chiral P,N-bidentate N-pyrrolylphosphines and their chelate complexes [Rh(η2-P,N)(CO)Cl] and [Pd(Allyl)(η2-P,N)]BF4 were synthesized by phosphorylation of (E,1R,2R,3R,5S)-2-[(2,6,6-trimethylbicyclo[3.1.1]heptyl-3-)iminomethyl]-1H-pyrrole. The composition and structures of the novel compounds were determined by the 1H, 13C, and 31P NMR, IR, mass spectrometry (electrospray), and elemental analysis methods. N-pyrrolylphosphines were found to have unusual electronic properties, being simultaneously more strong π-acids and σ-bases as compared to phosphites.
