Use of metal catalysts bearing Schiff base macrocycles for the ring opening polymerization (ROP) of cyclic esters [PDF]
© 2017 by the authors. Schiff base macrocycles are emerging as useful scaffolds for binding two or more catalytic metals in close proximity. Such coordination chemistry allows for the evaluation of potentially beneficial catalytic cooperative effects. In

Double Metal Alkoxides / Heterometallic Alkoxides
Heterometallic alkoxides are those alkoxides having two or more different metals linked via bridging alkoxy groups, via oxo-groups or sometimes metal-metal bonding. The large majority of heterometallic alkoxides corresponds to derivatives in which one of the metals is either an alkali or alkaline earth metal.

Metal alkoxides: Models for metal oxides: Alkoxide ligands in early transition metal organometallic chemistry [PDF]
An effort was made to compare and contrast the reactivity of trialkylsiloxide vs tert-butoxide supported dinuclear centers, and an initiative aimed at studying the syntheses of polynuclear hydridoalkoxides and their reactions has been implemented.

The ammonolysis of esters in liquid ammonia [PDF]
The rates of ammonolysis of alkyl benzoate and phenylacetate esters in liquid ammonia increase with the acidity of the leaving group alcohol and show relatively large Brønsted βlg values of −1.18 and −1.34, respectively, when plotted against the aqueous ...

Bis[N-(2-hydroxyethyl)-N-methylglycinato]copper(II)
The title compound, [Cu(C5H10NO3)2], was obtained unintentionally as the product of an attempted synthesis of a Cu/Cd mixed-metal mixed-anion complex using zerovalent copper, cadmium(II) oxide and two ammonium salts in the presence of 2 ...
