Recently, the already-known polymers of (5)-3-methyl-pentyne and (5 )-4-methyl-l-hexyne [27, 28] as well as of (5)-5-methyl-l-heptyne, (iS)-6-methyl-l-octyne and (S )-3,4-dimethylpentyne (Xlla—e) have been prepared in the presence of iron tris(acetylacetonate)-aluminum triisobutyl catalyst [29].

Takacs has reported the cyclization of tu-enedienes catalyzed by an iron(0) complex that is generated in situ through the reduction of iron(m) tris(acetylacetonate) with triethylaluminum in the presence of a ligand such as 2,2 -bipyridine or bisoxazoline (Scheme 100). The 1,4-diene cycloadducts are obtained in very good yields.366... 

The results published thereafter by Kochi s group are especially interesting from a mechanistic point of view . Indeed, for preparative chemistry the yields are not satisfactory and the reaction is limited to reactive alkenyl bromides such as propenyl and styryl bromides (Table 4). Neumann and Kochi were the first to replace iron(III) chloride by iron(III) acetylacetonate or related complexes such as Fe(dbm)3 (iron tris-dibenzoylmethanato) that are less hygroscopic and easier to handle.

Alkyl di-Grignard reagents can be reacted selectively with aliphatic and aromatic acid chlorides in the presence of tris(acetylacetonate)iron(III) [83]. The best conditions utilized alkyl chlorides in THF. Formation of alcohols is avoided in this one-step catalyzed...

The Fe(acac)3-x species are unstable on this surface so that the characteristic spectrum of iron acetylacetonate is not observed but instead a Fe-OH species is observed indicating that the iron has been grafted to the surface of the zirconia. The tris-Fe +(acac)3 does not decompose completely on other surfaces, such as silica and titania, but rather it may loose 1-2 ligands upon contacting the surface. Thus, the intrinsic chemistry of the surface can have a significant effect upon the reactivity of the Fe(acac)3 towards that surface. Upon heating to 300°C in air all evidence of the (acac) ligands had disappeared. 

Decomposition of methanesulphonyl azide in aromatic solvents (methyl benzoate or benzotrifluoride), in the presence of transition metal compounds (e.g. copper(ri) acetylacetonate, manganese(ii) acetylacetonate, di-cobalt octacarbonyl, tri-iron dodecacarbonyl, and iron pentacarbonyl) led to a marked decrease in the aromatic substitution product compared with thermolysis, and, with the iron carbonyls, to an increased yield of methanesulphonamide . In addition, the aromatic substitution products shifted from mainly ortAo-substitution with no additives to mainly w ia-substitution in the presence of the additives mentioned above.
