Iron nonacarbonyl

Iron ennecarbonyl (di-iron nonacarbonyl) [15321-51-4] M 363.7, m 100 (dec). Wash with EtOH and Et20 and dry in air. Sublimes at 35° at high vacuum. Dark yellow plates stable for several days when kept in small amounts. Large amounts, especially when placed in a desiccator spontaneously ignite in a period of one day. It decomposes in moist air. It is insoluble in hydrocarbon solvents but forms complexes with several organic compounds. [J Am Chem Soc 72 1107 7950 Chem Ber 60 1424 1927. ]... 

Unexpectedly, neither direct complexation nor the deoxygenated complexes 95 or 96136,137 were observed in the reaction of diphenylthiirene oxide (18a) with iron nonacarbonyl. Instead, the red organosulfur-iron complex 97138 was isolated12, which required the cleavage of three carbon-sulfur bonds in the thiirene oxide system (see equation 33). The mechanism of the formation of 97 from 18a is as yet a matter of speculation. 

Aniline has also been obtained (93%) from a homogenous reduction with preformed tetraethylammonium hydridotri-iron undecacarbonyl [10], In this reduction, the yield is comparable, or superior, to that obtained when the more reactive iron pentacarbonyl or di-iron nonacarbonyl complex is used in the absence of a phase-transfer catalyst.

Other carbonyls are prepared from iron pentacarbonyl. For example, iron nonacarbonyl is formed by decomposition of the pentacarbonyl when exposed to light. When nonacarbonyl in ether, benzene, or toluene is heated at 60°C, it produces dodecacarbonyl and pentacarbonyl ...

Today, we are studying whether iron can coordinate to aromatics and give, among other things, 77-benzyl derivatives. The 77-benzyl ligand is a modification of the 77-allyl one. So far, however, the coordination has been shown to be not too favorable. Actually ArCH2X (X is Cl, or Br) reacts with di-iron nonacarbonyl to produce, as a rule [437), ArCH2CH2Ar or... 

The 177-1,2-azaphospholes are colorless to yellow solids or oils and are stable at ambient temperature <20008417, 1998ICA(270)273, 2003ZNB44>. Most of the reactions reported so far involve the dicoordinated phosphorus atom, which represents the reactive center of the molecule. l,3-Di(fet/-butyl)-5-phenyl-177-l,2-diazaphosphole reacts under mild conditions with alkyl triflates CF38O3R (R = Me, Et) to afford the P-alkylated 1,2-azaphospholium compounds la and lb in quantitative yields. With an equimolar amount of iron nonacarbonyl, the Tj -complex 2 was selectively formed in 63% yield (Scheme 1) <2002EJ01664>.

Phenyl azide and di-iron nonacarbonyl react rapidly in benzene at room temperature (as compared with thermolysis of PhNg alone which occurs at temperatures of 140-170° ). The principal product was the orange phenyl nitrene-complex (387) which decomposed spontaneously in solution to give the urea-based complex (388). Also obtained in low yield was the orange complex (389). The yield of azobenzene was reported to be negligible. C)n the other hand, when the decomposition was carried out in benzene under reflux in the presence of Fe3(CO)i2j a significant amount of azobenzene was found . ...

Di-iron nonacarbonyl reacts with 2,5-dihydrothiophene to give the mononuclear complex [Fe(CO)4(C4H6S)j in which the heterocycle donates via the sulfur atomJ l Subsequent thermolysis brings about C S bond cleavage giving butadiene and an insoluble black material presumed to be FeS. Reaction of 2,5-dihydrothiophene with [Re2(CO)9(MeCN)j leads to a dirhenium product which features S-bound thiophene. This decomposes readily at 110 °C and butadiene is detected among the decomposition products. Because 2,5-dihydrothiophene does not decompose when heated at 120 °C over a period of three days, it can be concluded that the S-coordination of dihydrothiophene promotes decomposition with liberation of butadiene.
