Abstract
The reaction between Mo(CO)2(η3-C5H7)(CH3CN)2Cl and LiC9H7 or NaC13H9 gives (η5-C9H7)Mo(CO)2(η3-C5H7) (1) or (η5-C13H9)Mo(CO)2(η3-C5H7) (2) respectively. Photolysis of 1 with excess PMe3 and PMe2Ph in ether at - 20°C yields (η5-C9H7)Mo(CO)(PR3)(η3-C5H7) (PR3 = PMe3 (3), PMe2Ph (4)). Complexes 3 and 4 exist as exo and endo isomers and have been fully characterized by elemental analyses, and from their IR, mass, and 1H NMR spectra. The crystal structure of 1 has been determined by an X-ray diffraction study; crystallographic data: space group P21/C a 7.955(10), b 12.531(3), c 13.987(5) Å, β 100.86(7)°, Z = 4, R 2.4%, Rw 2.3%. © 1989.
