New reaction systems leading to cadmium, mercury and lead selenides and tellurides are reported. The chalcogenides were prepared by a simple, direct reaction between chalcogen, metal oxide or carbonate, and 3-(diphenylphosphino)propionic acid. The synthesis of 3-(diphenyltellurophosphoryl)propionic acid (1) is described and X-ray structures of 3-(diphenylphosphino)propionic acid (2) and its P[dbnd]E derivatives are presented, where E?=?O (3), S (4) and Se (5).

Two synthetic strategies for incorporating diiron analogues of [FeFe]-hydrogenases into short peptides via phosphine functional groups are described. First, utilizing the amine side chain of lysine as an anchor, phosphine carboxylic acids can be coupled via amide formation to resin-bound peptides. Second, artificial, phosphine-containing amino acids can be directly incorporated into peptides via solution phase peptide synthesis. The second approach is demonstrated using three amino acids each with a different phosphine substituent (diphenyl, diisopropyl, and diethyl phosphine). In total, five distinct monophosphine-substituted, diiron model complexes were prepared by reaction of the phosphine-peptides with diiron hexacarbonyl precursors, either (μ-pdt)Fe2(CO)6 or (μ-bdt)Fe2(CO)6 (pdt = propane-1,3-dithiolate, bdt = benzene-1,2-dithiolate). Formation of the complexes was confirmed by UV/Vis, FTIR and 31P NMR spectroscopy. Electrocatalysis by these complexes is reported in the presence of acetic acid in mixed aqueous-organic solutions. Addition of water results in enhancement of the catalytic rates.
