Reactivity of formaldehyde and acetaldehyde toward [N(CH2CH2PPh2)3]Ni and [N(CH2CH2PPh2)3]CoH

The Ni(0) complex (np3)Ni [np3 = tris(2-(diphenylphosphino)ethyl)amine] reacts with formaldehyde to give the paramagnetic Ni(I) formyl complex (np3)Ni(CHO), which decomposes to the diamagnetic Ni(0) carbonyl (np3)Ni(CO). Formaldehyde reacts with the Co(I) hydride (np3)CoH or with the methyl complex (np3)Co(CH3) to give the hydrido carbonyl compound (np3)Co(CO)H. When the latter reactions are carried out in the presence of NaBPh4, the cationic carbonyl [(np3)Co(CO)]BPh4 is formed. Acetaldehyde and propionaldehyde react with (np3)CoH yielding the corresponding paramagnetic η1-acyl complexes (np3)Co(COCH3) and (np3)Co(COC2H5). The reactivity of the acetyl derivative toward nucleophiles and electrophiles is investigated. Nucleophiles displace the acetyl ligand to give the corresponding complexes (np3)Co(Nu), whereas electrophiles remove the acetyl ligand to give the [(np3)Co]+ moiety. Possible reaction mechanisms are suggested on the basis of chemical and theoretical data.

Synthesis of Novel Mercury(I) Complexes containing a Linear Chain Co-Hg-Hg-Co. X-Ray Crystal Structure of the Complex >2(μ-Hg2)>*thf

Reduction of the cobalt(II) complexes BPh4 with sodium amalgam gives tetrametallic complexes of formula .The structure of 2(μ-Hg2)>*thf was determined from three-dimensional X-ray data collected by the counter method.The crystals are triclinic, space group P1, with a = 25.691(9), b = 13.387(5), c = 13.471(4) Angstroem, α = 119.56(8), β = 97.51(8), γ = 87.25(7) deg, and Z = 2.Full-matrix least-squares refinement converged at the conventional R factor of 0.067 for 2 687 observed reflections.The structure consists of dimeric units of 2) where the Hg2(2+) ion linearly bridges two Co(dppea) fragments.The dppea derivative reacts with carbon monoxide or carbon dioxide, at room temperature and atmospheric pressure, with formation of the carbonyl complex BPh4.

Reactivity of [N(CH2CH2PPh2)3]CoH toward CS2, SCNPh, OCNPh, and COS

Reaction of (np3)CoH (1) [np3 = tris[2-(diphenylphosphino)ethyl]amine] with CS2, SCNPh, or OCNPh affords (np3)Co(η2-CS2) (2), (np3)Co(η2-SCNPh) (6), and (np3)Co(η2-OCNPh) (8), respectively. In the presence of NaBPh4 1 reacts with CS2 or SCNPh to give [(np3)Co(CS)]BPh4 (3) and [(np3)Co(CNPh)]BPh4 (7), respectively, and with OCNPh or COS to give [(np3)Co(CO)]BPh4 (4). Methylation of 2 by MeSO3F, followed by NaBPh4 addition, leads to [Ph2PCH2CH2N(CH2CH 2PPh2)2Co(CS2Me)]BPh4 (5) through intramolecular attack by a phosphorus atom of np3 on a formed in situ η2-dithiomethyl ester group. On reaction of 5 with NaBH4 the P-CS2Me and C-SMe bonds are cleaved and the thiocarbonyl complex 3 is formed.
