Studies on Benzene-Azo-(Ethyl Acetoacetate) and Benzene-Azo(Acetyl Acetone ) as Chelating Agents

open access: yes, 1969
Co-ordination complexes of Cu(Il), Ni(Il), Co(II) and Co(III) with benzene-azo-(ethyl acetoacetate) and benzene-azo-(acetyl acetone) have been prepared. The pyridine adducts of some of these complexes have also been prepared. The magnetic moments and the electronic absorption spectra of the complexes have been reported and discussed.

Dipolar Molecular Motor Candidates with Planar Chirality

open access: yesChemistry – A European Journal, EarlyView.
Two prototypes of molecular motors with simultaneous implementation of planar chirality and a permanent dipole have been designed and synthesized in 7 steps with overall yields of 2.8 to 5.5%. Abstract Two molecular motor candidates built around ruthenium(II) centers featuring both planar chirality and a permanent dipole have been synthesized in seven ...

Methyl on the Bridge: 2‐Methyl Propellane as Precursor for 1,3‐Substituted 2‐Methylated Bicyclo[1.1.1]Pentanes

open access: yesChemistry – A European Journal, EarlyView.
The synthesis of 2‐methyl propellane and its conversion to various 1,2‐ and 1,2,3‐di‐ and trisubstituted bicyclopentanes is reported. Abstract Bicyclo[1.1.1]pentanes (BCPs) have emerged as isosteric replacements for mono‐ and para‐substituted benzene rings in medicinal and materials applications, involving substitution at the BCP bridgehead (1,3 ...

Report on the Benzene Study of 2008-2009 [PDF]

open access: yes, 2010
The purpose of this study was to determine whether reducing the amount of benzene in gasoline, which is scheduled to take place in 2011, will effect a change in indoor air benzene levels in Anchorage, Alaska.

The One‐Step Synthesis of Biologically Active Isochromans from Lignin‐Derived Aromatic Monomers in Tunable Deep Eutectic Solvents

open access: yesChemistry – A European Journal, EarlyView.
A straightforward one‐step protocol enables the synthesis of bio‐based and biologically active isochromans through the Oxa‐Pictet cyclization involving diverse aldehydes, including vanillin in combination with lignin‐derivable homovanillyl alcohol, a prominent aromatic platform chemical obtainable via diol‐assisted fractionation of lignocellulose ...

One‐Pot Transition‐Metal‐Free Methods for the Synthesis of All Three Bonds of the Alkyne's Triple Bond

open access: yesChemistry – A European Journal, EarlyView.
One‐pot transition‐metal‐free methods for the synthesis of all three bonds of the alkyne's triple bond are reviewed. After analysis of several named reactions and discussion of improvements, recent advances in the synthesis of alkynes are discussed. Each section contains a proposed reaction mechanism and analysis of the strengths and weaknesses of the ...
