Reaction-time resolved IR spectroscopy highlights the role of CO and surface –OCH3 in the MTO conversion catalysed by CoAPO-18 with maximised concentration of acidic sites.

The effect of differently substituted 2,2’-bipyridine ligands (i.e. 6,6’-dimethyl-2,2’-bipyridine, 5,5’-dimethyl-2,2’-bipyridine, 6,6’-dimethoxy-2,2’-bipyridine and 2,2’-bipyridine) on the reversible oxidation of the resulting Cu(I) homoleptic complexes is investigated by means of a multitechnique...

DES is exploited as a solvent media in Ullmann homocoupling of arenediazonium salts. Computational study supported by Raman spectroscopy is presented, aiming to elucidate the reaction mechanism.
