Electrochemistry of transition metal hydride diphosphine complexes trans-MH(X)(PP)2 and trans-[MH(L)(PP)2]+, M = Fe, Ru, Os; PP = chelating phosphine ligand was written by Drouin, Samantha D.;Maltby, Patricia A.;Rennie, Benjamin E.;Schweitzer, Caroline T.;Golombek, Adina;Cappellani, E. Paul;Morris, Robert H.. And the article was included in Inorganica Chimica Acta in 2021.Formula: C4H9NaS This article mentions the following:
A series of over 30 iron, ruthenium, and osmium hydride phosphine complexes are reported, along with their MIII/II redox potentials. The complexes are of the type MH(PP)n(X) or [MH(PP)n(L)]+, where PP is one of the following bidentate phosphine ligands: dppe, dtpe, depe, and dtfpe, with n = 2; or the tetradentate phosphine ligand meso-tet-1, with n = 1. The electrochem. data of these complexes and those from the literature are used to determine the Lever EL parameter of -0.65 V for the hydride ligand for iron and ruthenium. For osmium, however, the EL value for the hydride ligand is found to be more pos. at only -0.37 V, an increase which is attributed to Os-H 蟽 bond strengthening due to relativistic effects. The correlation holds for irreversible oxidations as well as reversible ones. These EL values can now be used along with Lever’s equations to predict redox potentials of other iron-group hydride complexes. In the experiment, the researchers used many compounds, for example, Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2Formula: C4H9NaS).
Sodium 2-methyl-2-propanethiolate (cas: 29364-29-2) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R鈥昈鈭?. For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Under carefully controlled conditions, simple alcohols can undergo intermolecular dehydration to give ethers. This reaction is effective only with methanol, ethanol, and other simple primary alcohols.Formula: C4H9NaS
