consisting of KI and metal acetate were tested in liquid phase oxidation of ethylene in acetic acid at various pressures. KI–Mn(OCOCH3)2 was found to be the most reactive system and a new material, CH3COOCH2CH2OCOCH2OCOCH3, was formed as a major byproduct. It was also found that the main product at an early stage of the reaction was ethylene glycol monoacetate, from which other products were formed consecutively
Liquid organic hydrogen carriers (LOHCs) are powerful systems for the efficient unloading and loading molecular hydrogen. Herein, a liquid‐to‐liquid organic hydrogen carrier systembased on reversible dehydrogenativecoupling of ethylene glycol (EG) with ethanol catalysed by ruthenium pincer complexes is reported. Noticeable advantages of the current LOHC system is that both reactants (hydrogen‐rich components)

The use of the oxidant 4-acetylamino-2,2,6,6-tetramethylpiperidine-1-oxoammonium tetrafluoroborate in combination with pyridine for the oxidative, dimeric esterification of primary alcohols is described. The ester is the predominant product of the reaction with alcohols containing a β oxygen. In the absence of a β oxygen, the corresponding aldehyde is found in appreciable amounts, but a concentration
