A slective one-step method is reported for the synthesis of Fe(CO)3(P-P) derivatives (P-P = chelating tertiary diphosphine), starting from FeCl2, diphosphine and manganese, in tetrahydrofuran, under a CO atmosphere, at room temperature.The use of manganese metal as reducing agent is essential for the selectivity of the process.In the absence of the reducing agent, complexes of the type Fe(CO)2(P-P)Cl2 have been obtained.All these iron compounds have been characterized by IR and 31P NMR spectroscopy.

On photolysis cis- (M = Fe, Ru; Os; DMPE = Me2PCH2CH2-PMe) and cis- (M = Fe, Ru, Os; DPPE = Ph2PCH2CH2PPh2) readily lose H2 by concerted coupling of the two hydrogen atoms.The photoreactions generate the extremely reactive intermed

The irradiation of solutions of cis-FeH2(DPPE)2 (1), DPPE = 1,2-bis(diphenylphosphino)ethane, with ultraviolet or visible light is an efficient method for preparing FeH(C6H4PPhCH2CH2PPh 2)(DPPE) (2). The 366-nm quantum yield for loss of hydrogen from 1 is 0.25 ± 0.05, and the chemical yield of crystalline 2 is 90%. Hydrogen (1 atm) reacts with solutions of 2 at 50°C to give 1 quantitatively and can be released irreversibly at 25°C by the photoconversion of 1 to 2. This cycle can be repeated without degeneration of the system. Protonation of 2 with formic acid gives 1 and CO2 and with fluoroboric acid under N2 gives trans-[FeH(N2)(DPPE)2]BF4. The decarbonylation of acetaldehyde by 2 provides a direct synthesis of Fe(CO)(DPPE)2. Products containing ortho-metalated PEtPh2 result as both H2 and N2 are photoeliminated from Fe(N2)H2(PEtPh2)3.
