TL;DR: In this paper, the first geometrical isomerization of thiolato-bridged dimolybdenum complexes induced by the transfer of two electrons at the same potential is reported.
31 citations
TL;DR: In this article, a mechanism involving an intramolecular elimination of CH4 from the initially formed insertion product (η5-C5H5)2MoH[Z-C(CO2CH3)CH(CO 2CH3)] is proposed for its formation.
10 citations
TL;DR: In this paper, direct reactions between organometallic complexes of iron and of cobalt are described in which an exchange of ligands (hexafluorobut-2-yne, cyclopentadienyl or carbonyl) takes place.

TL;DR: In this article, the substitution of P(OMe)3 for CO at the tungsten center is shown to have various effects on the electrochemical behavior of propylene carbonate.
Abstract: The compounds [(η5-C5H5)(CO)2[graphics omitted](CO)4L](1)(L = CO) and (2)[L = P(OMe)3] have been studied by electrochemical methods (cyclic voltammetry, controlled-potential electrolysis, and coulometry) in propylene carbonate. The substitution of P(OMe)3 for CO at the tungsten centre is shown to have various effects on the electrochemical behaviour. Both (1) and (2) are reduced according to an e.c.-disp. process (second electron transfer is homogeneous) which differs depending on the nature of L. The results reported are consistent with the presence of an acceptor–donor metal–metal bond in both compounds.

TL;DR: The ethenylidenediiron complex [C5H5Fe(CO)]2 (μ-CO)(μ-CCHCH(CN)H) as mentioned in this paper reacts with the nitrile substituted alkyne HCCCn to give high yield of [(C 5H5)Fe[C5]Fe[CO] 2 (μ]-CO)

TL;DR: In this article, a destructive two-electron reduction according to an electrochemical-chemical-electrochemical process with a diffusion-controlled intervening chemical step is described, leading to the dinuclear species [W2(CO)10(µ-SMe)] on the time-scale of controlled potential electrolyses.
Abstract: The compounds [(η5-C5H5)(CO)3M(µ-SR)W(CO)5] have been studied by usual electrochemical methods (cyclic voltammetry, controlled-potential electrolysis, and coulometry). They undergo a destructive two-electron reduction according to an electrochemical–chemical–electrochemical process with a diffusion-controlled intervening chemical step. The [W(CO)5(SMe)]– anion generated by the reduction of the complexes undergoes chemical reactions leading to the dinuclear species [W2(CO)10(µ-SMe)]– on the time-scale of controlled-potential electrolyses.
