Synthesis of μ-Phosphido Diiron Complexes Having a P−H Bond: Hydrophosphination of Phenylacetylene and Methyl Acrylate with the Cationic μ-Phosphido Diiron Complex

“…Functionalization of an E-H group (E ) heteroatom such as Si and P) in the organometallic or organoheteroatom ligands coordinated to transition-metal complexes has attracted increasing interest as an important method in synthetic organometallic chemistry. [1][2][3][4] Although the majority of the known such reactions need some additives such as radical initiator or base to activate the E-H bond or to abstract the proton from the E-H group, direct functionalization of the E-H group without any additive would be preferable from the viewpoint of atom economy. In relation to this, we previously reported the synthesis and reactivity of silylene-and germylene-bridged diiron complexes having an E-H bond, Cp 2 Fe 2 (CO) 2 (µ-CO)(µ-EHR) (E ) Si, Ge).…”

First Crystal Structure of a Cyclohexasilyl Transition-Metal Derivative, [(DIME)2Li][Mo(CO)5Si6Me11] (DIME = Diethylene Glycol Dimethyl Ether)

“…Analysis of the 15 existing structures shows that the average values for Mo−Si bonds are in the range of 2.538−2.608 Å 10d and one example of an extremely long bond is in tetrakis(dimethylamino)bis(tris(trimethylsilyl)silyl)dimolybdenum 10a with a bond length of 2.669 Å. The bond length of 2 is also very long compared to the literature data.…”
