Optically Active Transition Metal Compounds, 136 [1]. An Octahedral Molybdenum Complex (P-P’)Mo(CO)4 with a Chiral Secondary Phosphorus Atom

Zusammenfassung

Reaction of (eta(6)-C6H5CH3)Mo(CO)(3) with the easily accessible chiral chelate ligand P,P,P'-tris-[(+)-9-phenyldeltacyclan-8-yl]-1,2-bis(phosphanyl)benzene P-P' afforded the octahedral molybdenum carbonyl derivate (P-P')Mo(CO)(4) 1 as a diastereomer mixture 1a (74%) and 1b (26%). Crystallization gave single crystals of (Sp)-(P-P')Mo(CO)(4) 1a. The X-ray structure analysis of compound 1a revealed the formation of an unusual triple-decker pi-stack in the solid state.
