Double bonds activated by the presence of electron withdrawing groups (NO2, CO2Et, COMe, CN) can be cleaved by use of ethanethiol and a hard Lewis acid such as AlCl3, AlBr3, FeCl3 or ZnCl2 to give dithioacetals in good yields.174,175 For example, dicyanostyrene (12) can be converted...

Organic chemistry is the study of carbon-containing compounds, while inorganic chemistry is the study of non-carbon-containing compounds. Additionally, organic compounds tend to have covalent bonds and are often found in living organisms, while inorganic compounds tend to have ionic bonds and are oft...
Dimerization and catamerization of adsorbed HCN may be monitored using the bulk libration at 26 meV and the C-H stretching mode. Strong multiple scattering effects are observed in solid HCN films. 展开 关键词: Experimental/ chemisorption desorption electron energy loss spectra hydrogen bonds hydrogen...
The complexes dichloro[(1,2,5,9-η4)-5-methylenecyclooctene]platinum(II) (4a) and dibromo[(1,2,5,9-η4)-5-methylenecyclooctene]platinum(II) (4b), each of which has an unusual "in-plane" coordinated olefin (C5C9), show marked reactivity enhancements compared to typical dihalo(η4-...

In the field of chemical kinetics, the proposed technique can supply information on the importance of elementary steps in complex reaction mechanisms. As examples, high-temperature propane pyrolysis and the chemistry of the "unpolluted" troposphere are studied....
The reactivity of the carbon−carbon double bond differs from the chemical surroundings of the double bonds. The oxidation of the double bonds in the aliphatic chains just requires the use of hydrogen peroxide [18]. However, stronger oxidative reagents such as m-chloroperbenzoic acid (m-CPBA)...
