[reaction: see text] A new one-pot tandem aldol process is described in which a secondary epoxy silyl ether is converted into the 1,5-bis-silyloxy-3-alkanone in good yield. Thus, treatment of the epoxy silyl ether 8 with TBSOTf and base affords the silyl enol ether 9 via non-aldol aldol rearrangement and addition of benzaldehyde and TBSOTf gives the ketone 10 with 4:1 syn selectivity. The diast...

A tandem organosolv pulping and Pd-catalysed transfer hydrogenolysis depolymerisation and deoxygenation has been developed. The tandem process generated 2-methoxy-4-(prop-1-enyl)phenol in 23% yield (92% theoretical monomer yield) starting from pine wood and 2,6-dimethoxy-4-(prop-1-enyl)phenol in 49% yield (92% theoretical monomer yield) starting from birch wood. Only endogenous hydrogen from wo...

Electrochemical CO2 reduction (CO2R) in acidic media with Cu-based catalysts tends to suffer from lowered selectivity towards multicarbon products. This could principle be mitigated using tandem catalysis, whereby the *CO coverage on Cu is increased by introducing a CO generating catalyst (e.g. Ag) close proximity. Although this has seen significant success neutral/alkaline media, here we repor...

CO2 Reduction Reaction In article 2203506, Lin Gu, Xiao Li, Hong Liu, Weijia Zhou, and co-workers aim to solve the problems of poor adsorption capacity weak *H supply in Cu-Sn alloys, by designing SnO2/Cu6Sn5/CuO nanocatalysts with superscalar phase boundaries. This strategy tandem electrocatalytic reduction reaction (CO2RR) multiple active sites reduced barrier process, resulting excellent CO2...
