Complexes trans- (II: L=CNR; R=Me, But, C6H4OMe-4 or C6H4NO2-4.III: L=N2; dppe=Ph2PCH2CH2PPh2) have been obtained from the reaction of trans- (I) with the appropriate ligand L in the presence of TlBF4.In cyclic voltammetry, at a sufficiently low scan rate, compound II (R=Me) undergoes an anodic ECE process, with metal-hydride bond rupture (proton loss) and metal fluorination, to give trans-, which has been electrosynthesized by CPE.
Photochemical synthesis and reactions of FeH(C6H4PPhCH2CH2PPh 2)(PPh2CH2CH2PPh2)

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.
