A team of chemists at the University of Cambridge has developed a powerful new method for adding single carbon atoms to molecules more easily, offering a simple one-step approach that could accelerate ...

Three long-chain alkanes detected by Nasa’s Curiosity rover could be ... However, the compounds could also have been produced by abiotic chemical reactions. Reporting on the findings, the researchers ...

Abstract: A convenient synthesis of vicinal methoxychlorides, methoxyiodides from alkenes and alkynes using PhICl/sub 2//CH/sub 3/OH, I/sub 2//PhICl/sub 2//CH/sub 3/OH is described. Published in: ...

The Pauson–Khand reaction is a metal-mediated [2+2+1] cycloaddition of an alkene, an alkyne, with carbon monoxide to construct an α, β-cyclopentenone skeleton. As shown in Figure 2E-III, in the total ...

Beisson and colleagues knew that some species of microalgae could convert long-chain fatty acids to alkanes or alkenes ... as a redox cofactor in biological reactions. In the case of FAP, however ...

The PKR is a [2+2+1] cycloaddition that involves a reaction between an alkene, alkyne and carbon monoxide (CO). Its catalytic form requires the use of a constant external source of carbon monoxide to ...

One reaction that’s been hovering on the edge of relevance for a few years is alkyne metathesis, which is generally viewed as a poor cousin to the Nobel-winning alkene version, despite being ...

alkene, alkyne, and nitro groups). Moreover, the NACs catalysts are robust with consistent selectivity and activity for both liquid and gas phase reactions under high temperature and/or pressure.

This section will include questions on general topics, gaseous and liquid states, atomic structure and chemical bonding, energetics, chemical equilibrium, electrochemistry, chemical kinetics ...
