Reaction of lithium dimethyl cuprate with carbonyl iron a,ß-unsaturated ketone complexes: The structure of a novel ?3,? 3-[(1,6-diphenyl)-3,4-(distyr-1-yl)-1,3,5-hexatriene]-Fe(CO) 2 complex

Resumen:
The reaction between ?4-?,?-unsaturated ketone-Fe(CO)3 complexes and Me2CuLi in the absence of CO atmosphere yields the corresponding ?4-vinylketene complexes 2, 4 and 6. The reaction between ?2-dibenzylideneacetone-Fe(CO)4 and Me2CuLi gives a new dimeric complex 8, which was characterized by mass spectrometry, IR, 1H and 13C NMR spectroscopy and its structure confirmed by single-crystal X-ray analysis. © 1997 Elsevier Science Ltd.
