REACTION OF LITHIUM DIMETHYL CUPRATE WITH CARBONYL IRON ALPHA,BETA-UNSATURATED KETONE COMPLEXES - THE STRUCTURE OF A NOVEL NYL)-3,4-(DISTYR-1-YL)-1,3,5-HEXATRIENE]-FE(CO)(2) COMPLEX
O. Garciamellado et al., REACTION OF LITHIUM DIMETHYL CUPRATE WITH CARBONYL IRON ALPHA,BETA-UNSATURATED KETONE COMPLEXES - THE STRUCTURE OF A NOVEL NYL)-3,4-(DISTYR-1-YL)-1,3,5-HEXATRIENE]-FE(CO)(2) COMPLEX, Polyhedron, 16(17), 1997, pp. 2979-2985
The reaction between eta(4)-alpha,beta-unsaturated ketone-Fe(CO)(3) co
mplexes and Me2CuLi in the absence of CO atmosphere yields the corresp
onding eta(4)-vinylketene complexes 2, 4 and 6. The reaction between e
ta(2)-dibenzylideneacetone-Fe(CO)(4) and Me2CuLi gives a new dimeric c
omplex 8, which was characterized by mass spectrometry, IR, H-1 and C-
13 NMR spectroscopy and its structure confirmed by single-crystal X-ra
y analysis. (C) 1997 Elsevier Science Ltd.
