    摘要： The present invention relates to a process for preparing unsymmetric compounds from the group of the m-terphenyls which can be used as unsymmetric OCO pincer ligands, comprising the process steps of a) reacting a first substituted or unsubstituted phenol with a 1,3-disubstituted arene which may likewise be substituted in the 2 and 5 positions to obtain a phenol-arene coupling product and b) optionally protecting the OH group of the phenol-arene coupling product with a protecting group to obtain a protected phenol-arene coupling product, and c) reacting the phenol-arene coupling product from a) or b) with a second substituted or unsubstituted phenol to obtain an unsymmetric m-terphenyl, with the proviso that the first phenol and the second phenol have different substitution, characterized in that at least one of process steps a) and c) is conducted as an electrochemical process step.

    摘要： The present disclosure includes a system and method for producing a first product from a first region of an electrochemical cell having a cathode and a second product from a second region of the electrochemical cell having an anode. The method may include a step of contacting the first region with a catholyte comprising carbon dioxide, producing a first product which may include carbon monoxide or an alkli metal formate. The method may include another step of contacting the second region with an anolyte comprising a sulfur-based reactant and producing a second product including oxygen and sulfur dioxide. Further, the method may include a step for introducing the separated oxygen from second region of the electrochemical cell with a hydrogen sulfide stream in a catalyst reactor bed, converting the hydrogen sulfide to sulfur dioxide. The sulfur dioxide may then be liquefied as a product, or a portion of the sulfur dioxide may be recycled to the second region of the electrochemical cell where it may be converted to sulfuric acid. The sulfuric acid may then be reacted with another reactant, such as ammonia, to produce an ammonium sulfate product.
