An efficient hydrogenation of various alkenes using scrap automobile catalyst

The Dibenzosuberenone Scaffold as a Privileged Substructure: From Synthesis to Application

“…Scrap automobile catalyst was used for hydrogenation of 5-dibenzosuberenone (1) to give dibenzosuberone (6) in an efficient, cheap, and green procedure (Figure 22). 154 The reaction of molecular bromine and chlorine with alkenes to yield vicinal dihalides via anti-addition is one of the oldest-known…”

Continuous flow synthesis of menthol via tandem cyclisation–hydrogenation of citronellal catalysed by scrap catalytic converters

“…30 Furthermore, the direct applicability of SCATs in catalysis have been previously demonstrated in simple batch experiments. [31][32][33]…”

Scrap waste automotive converters as efficient catalysts for the continuous-flow hydrogenations of biomass derived chemicals

“…[16][17][18][19] Only a few studies described SCATs as catalysts (e.g., for the reduction of nitroarenes with NaBH 4 ) but the reactions to date have been strictly limited to batch conditions. [20][21][22] In the present work, SCATs were exploited as cheap, efficient and environmentally friendly catalyst in a continuous flow hydrogenation system. To the best of our knowledge, no similar work has been previously described.…”
