“…60 Recently an activated carbon supported Pd−Au BMC has achieved a 5 times higher TOF value for oxidation of methyl-glucoside to glucuronic acid than its respective monometallic forms. 61 The CNTs belong to a superior material category with characteristic physiochemical features such as excellent mechanical property, high specific surface, brilliant electron conductivity, and good chemical and thermal stability. Furthermore, minimum aggregation of catalyst nanoparticles (NPs) and heterogeneity deterioration have been observed in CNTs because of their inert behavior, which encouraged researchers to select them as supporting materials for catalysis in order to avoid the ambiguity for predicting the mechanistic pathways.…”

Supported Pd−Au bimetallic catalysts (BMCs) have attracted remarkable research interest because they can efficiently execute various important organic transformations. The major concern for launching Pd−Au bimetallic catalysis is either to perform the reaction with good atom economy under low catalyst/ metal loading or to introduce a reaction, which cannot be performed by its monometallic variants. The supports being applied for Pd−Au alloy also have been examined for their crucial role to perform a particular reaction accredited to combined synergistic effects in the catalyst. The optimized tuning between the catalyst support and the Pd/Au ratio always have been a deciding key factor for selectivity, stability, and activity of these catalysts as suggested by various mechanistic studies. Herein, we have summarized the recent advances in supported Pd−Au BMCs in terms of design strategies, characterizations for deep insight mechanistic study during the reaction course. This Review begins with a brief history and adopted methods for preparation of these catalysts followed by categorization of supporting material being applied either directly or after modification. Furthermore, quick glances of catalyst characterization, effects on conversion and selectivity, catalyst activation, and deactivation under the studied reaction parameters for respective organic transformations also have been included in the above-mentioned sections. The main purpose of catalyst development is to accomplish easy access of tedious reactions with good conversion rate and selectivity toward desired product. Therefore, in view of the application part for Pd−Au BMCs, we have tried to cover all basic and important organic reactions along with their substrate scope range and mechanistic studies. This present Review could be really useful for researchers working in this dimension via providing them a clear catalyst design idea, preparation method, support selection strategy, and right substrate screening for carrying out the targeted synthetic transformation.

“…In addition, it was proposed that GUA could be synthesized by an indirect pathway, where methylation is required before oxidation, to avoid oxidation on C1 (i.e., formation of GOA), and hydrolysis is then necessary to obtain GUA. 16 Nonetheless, the highest yield of methoxy-protected GUA was 46%, limiting the practical value of this pathway.…”
