  • METHOD FOR THE SELECTIVE CLEAVAGE OF A COMPOUND COMPRISING AN AROMATIC RING AND A C-O-C LINKAGE
    Publication number: 20240043626
    Abstract: A method for the selective cleavage of a compound comprising an aromatic ring and a C—O—C linkage in the presence of a heterogeneous catalyst is provided. The heterogenous catalyst may be a supported noble metal catalyst doped with a halogen selected from the group consisting of chlorine and bromine. By using this method, it is possible to increase the selectivity and/or yield (preferably both) of aromatic compounds.

  • METAL-IODIDE CATALYTIC SYSTEM FOR DIRECT ETHERIFICATION FROM ALDEHYDES AND/OR KETONES
    Publication number: 20210237040
    Abstract: A process for etherification of aldehydes and/or ketones in the presence of a catalyst and an iodine source. In particular, a process for the synthesis of an ether compound, comprising reacting an aldehyde and/or a ketone with an alcohol, in the presence of (i) a metal/support heterogeneous catalyst and an iodine source, or (ii) a metal-iodine catalyst, in a reactor, whereby the ether compound is obtained. A catalytic system comprising a metal/support heterogeneous catalyst and an iodine source, and a process for its preparation.
