Several polyols, which are easily available from sugars through biochemical conversion or hydrogenolytic cleavage, are directly converted into carboxylic acids and amides. This efficient dehydrogenative coupling process, catalyzed by a rhodium(I) diolefin amido complex, is an attractive approach for the production of organic fine chemicals from renewable resources. This method tolerates the presence of several hydroxy groups and can be extended to the direct synthesis of lactams from the corresponding amino alcohols under mild conditions.

“…In the course of our studies on direct alcohol fuel cells (DAFC), we developed a new type of fuel cell called an organometallic fuel cell (OMFC), for which the anode electrocatalyst is a molecular metal complex embedded in a conductive carbonaceous material. These electrocatalysts efficiently catalyze the conversion of primary alcohols and polyols into the corresponding carboxylic acid derivatives and at the same time produce electrical power . Related work with other complexes as active sites on conductive support materials has demonstrated that this approach may be broadly applied to the development of electrocatalysts used in fuel cells, as well as for hydrogen production.…”

The selectivea nd simultaneous productiono fh ydrogen and chemicals from renewable alcohols was accomplished by using an electrolyzer,f or which the anode electrocatalyst was an organometallic complex, [Rh(OTf)(trop 2 NH){P(4-BuC 6 H 4 ) 3 }] (trop 2 NH = bis(5H-dibenzo[a,d]cyclohepten-5-yl)amine; À OTf = CF 3 SO 3 À ), deposited on amorphous carbon and appropriately designed to promote the partial and selective oxidation of alcohols. The electrolyzer converted alcohols into industriallyr elevant chemicals and high-purity hydrogen at high volume and with very low energy consumption.[b] Q.

The ORCID identification number(s) for the author(s) of this article can be found under https://doi.org/10.1002/smtd.201800059.The field of molecular electrocatalysis research includes a wide range of emerging technologies that utilize molecular catalysts to catalyze anodic and/ or cathodic reactions within a fuel-cell setup, and has developed greatly in the last 10 years. Although the vast majority of fuel cells utilize noble metals as catalysts, several systems have been recently developed that are based on molecular catalysts. The focus here is on the integration of molecular catalysts in a fuel-cell setup, which is contextualized, and which is named as "fuel-cell-based molecular-type catalysts" here. The latter utilize a wide variety of chemical compounds, such as organometallics and organic or bioinspired compounds, to harvest chemical energy to generate current. Here, the stateof-the-art for all molecular catalysts that convert chemical energy in a fuel-cell setup is discussed and a novel classification system is presented to illustrate how molecular catalysts integrate into the broad field of fuel cells. The current performance of molecular catalysts in systems that use different fuels is summarized, and finally, for the first time, the achievable power outputs of fuel cells using uniquely molecular catalysts are presented.
