Syntheses of new Fe/Se clusters via the reactions of PhC(Se)NHCH2Ph, Et3N and Fe3(CO)12 with electrophiles

Panoply of P: An Array of Rhenium–Phosphorus Complexes Generated from a Transition Metal Anion

“…This is especially true of O -substituted phosphido ligands, P­(OR) 2 – , which tend to be much less sterically inhibited than N - or C -substituted phosphido ligands. While there are many examples of bridging P­(OR) 2 – ligands, − there are only two other crystallographically characterized transition metal complexes with a P­(OR) 2 – ligand bonding in a terminal fashion. , In 2 – 4 , the bulky β-diketiminate ligand plays an important role in preventing dimerization, particularly for complex 4 which contains a rather small O -heterocyclic phosphido ligand.…”

Syntheses, crystal structures, and electrochemical studies of diiron complexes from the reactions of [Et3NH][(μ-RS) Fe2(CO)6(μ-CO)] with isothiocyanates

“…The MeO 2 CCH 2 group of 1 as two singlets appears at 3.636 and 2.829 ppm. Unlike 1, the MeO 2 CCH 2 group in 2 exhibits one singlet at 3.805 ppm and one typical AB quartet due to coupling between the two magnetically nonequivalent protons of the CH 2 group, with a 2 J of 13.6 Hz [19, 22(a), 23]. The pyridyl group shows one multiplet for 1, and two doublets and one singlet for 2.…”

“…Synthetic complexes of nickel, cobalt, iron, and molybdenum have been developed as electrocatalysts for the production of hydrogen [13,14]. We have recently initiated a project developing synthetic methodologies towards iron-sulfur and iron-selenium cluster complexes as model compounds [15][16][17][18][19][20][21][22][23]. As part of this on-going project, we report herein the syntheses, crystal structures, and electrochemistry of diiron complexes with thiocarbamoyl groups.…”
