Cleavage

In the chemical industry, the selective cleavage and oxidation of carbon–hydrogen (C–H) bonds, called “oxidative C–H functionalization” is an essential step in the production of many solvents, polymers, and surfactants, as well as intermediate compounds for agrochemicals and pharmaceuticals.

Rai-Shung Liu and co-workers at the National Tsing-Hua University, in Hsinchu, have reported a gold-catalysed procedure for the oxidative cleavage of aryl-substituted alkynyl ethers using molecular oxygen. ‘This work serves the first example that a C-H, single and triple carbon-carbon bonds can be more

Weizmann Institute scientists have devised a unique new mechanism for the formation of hydrogen and oxygen from water, without the need for sacrificial chemical agents, through individual steps, using light. The design of efficient systems for splitting water into hydrogen and oxygen, driven by sun more

The divalent samarium triflate salt does not react with CO2 or water, but does react with traces of O2 or N2O to form a tetrameric bis-oxo samarium motif. The reaction with O2 is a 4e− reductive cleavage where the electrons are coming from four different samarium centers. This highlights a rare syne more

Polar perovskite oxides are of considerable interest for developing advanced functional materials with exceptional electronic properties for their unique polar characters. A cleavage of polar perovskite oxides along the charged layers leads to an electrostatic instability on the cleaved surfaces, an more

The redox behaviour of the dimeric tetrairon complex, ([fc(NPiPr2)2]Fe)2 (where fc(NPiPr2)2 = 1,1’-(C5H4NPiPr2)2Fe) has been investigated. Upon reduction with KC8 a Fe-Fe bond is formed with the complex maintaining a high spin configuration and having the formula [K(THF)6]([fc(NPiPr2)2]Fe)2. In cont more
