Promoting Alkane Binding: Crystallization of a Cationic Manganese(I)‐Pentane σ‐Complex from Solution
Angewandte Chemie International Edition, Volume 64, Issue 27, July 1, 2025.Oxidation of Mn₂(CO)₁₀ under pseudo gas‐phase conditions generates the weakly coordinated 16 valence electron complex [Mn(CO)₅]⁺, which binds n‐pentane as the strongest ligand available in this system. Three isomers were characterized by low‐temperature NMR and X‐ray crystallography.

Inorganica Chimica Acta, 1998 Abstract The thermal and photochemical reactions of CpRe(PPh3)2H4 and CpRe(PPh3)H4 (Cp = η5-C5H5) with PMe3, P(p-tolyl)3, PMe2Ph, DMPE, DPPE, DPPM, CO, 2,6-xylylisocyanide and ethylene have been examined. While CpRe(PPh3)2H2 is thermally inert, it will undergo photochemical substitution of one or two PPh3 ligands.
