Reaction of lithium dimethyl cuprate with carbonyl iron α,β-unsaturated ketone complexes: The structure of a novel η3,η 3-[(1,6-diphenyl)-3,4-(distyr-1-yl)-1,3,5-hexatriene]-Fe(CO) 2 complex

The reaction between η4-α,β-unsaturated ketone-Fe(CO)3 complexes and Me2CuLi in the absence of CO atmosphere yields the corresponding η4-vinylketene complexes 2, 4 and 6. The reaction between η2-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.

Addition of phosphonoacetate anions to tricarbonyl(vinylketene)iron(0) complexes gave tricarbonyl(vinylallene)iron(0) complexes.Stereoselectivity as high as 98:2 was observed and the relative stereochemistry of the major stereoisomers was elucidated by X-

Alkynes add to (vinylketene)tricarbonyliron(0) complexes to generate stable adducts; addition of unsymmetrical alkynes is highly regioselective and the regiochemistries of the adducts produced in these reactions were determined by X-ray crystal structure

Reaction of tricarbonyl(η4-vinyl ketone)iron(0) complexes (CO)3(PhCH=CHC(R)=O)Fe(O) (R = Me, 1; Bun, 3; But, 5; Ph, 7) with organolithium reagents under an atmosphere of carbon monoxide gave products that were identified as tricarbonyl (η4-vinylketene) iron(0) complexes (CO)3(PhCH=CHC(R)=C=O)Fe(0) (R = Me, 2; Bun, 4; But, 6; Ph, 8) based on a crystal structure analysis of 2. Complex 2 crystallizes in space group P21/c with a = 13.998 (6) A?, b = 7.955 (5) A?, c = 12.935 (5) A?, β = 113.04 (3)°, and Z = 4. A reaction pathway that postulates the intermediacy of a tricarbonyl(η3-vinylcarbene)iron(0) complex, 20, is discussed. Heating the tricarbonyl(η4-vinylketene)iron(0) complexes 6 and 2 with either tert-butyl, cyclohexyl, or 2,6-xylyl isocyanide at 80°C gave tricarbonyl (η4-vinylketenimine) iron(0) complexes (CO)3(PhCH=CHC(R1)= C=NR2)Fe(0) (R1 = R2 = But, 23; R1 = Me, R2 = But, 24; R1 = Me, R2 = C6H11, 25; R1 = Me, R2 = (2,6-Me2)C6H3, 26) via intermediate dicarbonyl(isocyanide)(η4-vinylketene)iron(0) complexes. The intermediacy of tricarbonyl(isocyanide)(η1-vinylcarbene)iron(0) complexes in this reaction is proposed.
