Azidophosphonamido Rhodium(I) and Iridium(I) Complexes: Synthesis, Properties, and Linkage Isomerism

Chemistry – A European Journal, EarlyView.
A family of azidophosphonamido ligands and their corresponding rhodium(I) and iridium(I) complexes were synthesized. The rich reaction chemistry of these species revealed unusual linkage isomerization processes and bonding motifs. M = Rh, Ir; Mes = 2,4,6‐Me3C6H2. ABSTRACT A series of azidophosphonamido rhodium(I) and iridium(I) complexes ([iPr2P(N3R)NR]

Silica‐Supported Mononuclear Methyl‐Platinum Complexes Stabilized by Trimethylphosphine—Synthesis, Structure, and Reactions Under Reducing Conditions

Chemistry – A European Journal, EarlyView.
The article describes the synthesis and molecular transformations of a silica‐supported bis(phosphine)methylplatinum(II) complex under reactive (H2, CO) and inert gas atmospheres. The focus lies on the stabilizing effect of the sterically non‐demanding trimethylphosphine ligand, which alters the reactivity of the surface sites, compared to other ...
