Abstract
Intramolecular [4 + 2] Diels-Alder cycloaddition reactions of cis(alle nylphosphine) (3,4-dimethyl-1-phenylphosphole) tetracarbonylmolybdenum complexes occur regioselectively at the allenyl C-alpha = C-beta doub le bond to form hosphino-3-exo-methylene-7-phosphanorbornenetetrac arb onylmolybdenum complexes. Analogous ropargylphosphine)(3,4-dimethyl-1- phenylphosphole) tetracarbonylmolybdenum complexes do not undergo intr amolecular cycloadditions. The new complexes were characterized by ele mental analyses, physical properties, H-1, C-13(H-1), P-31(H-1) NMR sp ectroscopy, infrared spectroscopy and X-ray crystallography.
