Double Molecular Recognition with Aminoorganoboron Complexes: Selective Alcoholysis of β-Dicarbonyl Derivatives

Double Molecular Recognition with Aminoorganoboron Complexes: Selective Alcoholysis of β-Dicarbonyl Derivatives:

Double duty: Aminoorganoboron (AOB) complexes recognize alcohol and β-dicarbonyl units, and thereby facilitate chemo- and site-selective alcoholysis of the latter (see scheme). The complex activates both reaction partners. This strategy enables CC, CN, and CO bond cleavage in addition/elimination reactions under near neutral pH conditions and provides a new method for functional group conversions.
We work with a lot of dicarbonyls

Structural and Spectroscopic Characterization of a Monomeric Side-On Manganese(IV) Peroxo Complex

Structural and Spectroscopic Characterization of a Monomeric Side-On Manganese(IV) Peroxo Complex:

Gotcha: The binding and activation of oxygen by a manganese complex is reported. A PS₃ coordination sphere built around a manganese(I) center facilitates the isolation of a monomeric manganese(IV) peroxo complex that is stable at ambient temperature (see picture). The activation of molecular oxygen is proposed via a manganese(II) intermediate with an empty site for the binding of the substrate.

Towards a Green Process for Bulk-Scale Synthesis of Ethyl Acetate: Efficient Acceptorless Dehydrogenation of Ethanol

Towards a Green Process for Bulk-Scale Synthesis of Ethyl Acetate: Efficient Acceptorless Dehydrogenation of Ethanol:

Green is a go: An efficient acceptorless dehydrogenative dimerization of ethanol to give ethyl acetate was realized (see scheme). The reaction proceeds under mild reaction conditions in the presence of a ruthenium catalyst with concomitant liberation of molecular hydrogen, which can be used as a valuable product itself. At low catalyst loading (50 ppm), high yields of ethyl acetate and excellent catalyst turnover numbers are achieved.

Confused HCl: Hydrogen Chloride or Hydrochloric Acid?

Confused HCl: Hydrogen Chloride or Hydrochloric Acid?:

Hydrogen chloride can exist in various forms. Indiscriminative uses of the abbreviation “HCl” for its different forms has led to considerable confusions in the literature. The discovery of hidden solid forms of widely studied molecules using different forms of hydrogen chloride highlights the need of clarifying terminology surrounding hydrogen chloride in chemical research (see figure).

RA: Great Review of General Interest.


Nature 484, 7393 (2012). doi:10.1038/nature11008

Authors: Amanda J. Hickman & Melanie S. Sanford

Copper and palladium catalysts are critically important in numerous commercial chemical processes. Improvements in the activity, selectivity and scope of these catalysts could drastically reduce the environmental impact, and increase the sustainability, of chemical reactions. One rapidly developing strategy for achieving these goals is to use ‘high-valent’ organometallic copper and palladium intermediates in catalysis. Here we describe recent advances involving both the fundamental chemistry and the applications of these high-valent metal complexes in numerous synthetically useful catalytic transformations.

Group,

I think it is targeting organic chemist, but what are functional groups if not ligands for us inorganic chemists.

Phosphorus as a Lewis Acid: CO2 Sequestration with Amidophosphoranes

Phosphorus as a Lewis Acid: CO2 Sequestration with Amidophosphoranes:

CO₂snapper: Compounds containing both acidic and basic P,N functionalities have been prepared. Of these, two amidophosphoranes containing highly reactive PN bonds within four-membered rings react rapidly with CO₂, resulting in relief of ring strain. These compounds demonstrate the utility of phosphorus as a Lewis acid for small-molecule activation.
