Palladium/Rhodium Cooperative Catalysis for the Production of Aryl Aldehydes and Their Deuterated Analogues Using the Water–Gas Shift Reaction

A novel Pd/Rh dual-metallic cooperative catalytic process has been developed to effect the reductive carbonylation of aryl halides in moderate to good yield. In this reaction, water is the hydride source, and CO serves both as the carbonyl source and the terminal reductant through the water–gas shift reaction. The catalytic generation of the Rh hydride allows for the selective formation of highly hindered aryl aldehydes that are inaccessible through previously reported reductive carbonylation protocols. Moreover, aldehydes with deuterated formyl groups can be efficiently and selectively synthesized using D2O as a cost-effective deuterium source without the need for presynthesizing the aldehyde.

Friedel-Crafts Reaction of 2-Methylfuran with Saturated and α,β-Unsaturated Acid Anhydrides

2-Methylfuran (5) reacts with the saturated acid anhydrides 16 - 26 in the presence of SnCl4 to give the 2-acyl-5-methylfurans 37 - 47 selectively.The unsaturated anhydrides 27 - 32, however, yield mixtures which only in the case of senecioic acid anhydride (29) contain the respective primary product 48.Subsequent reactions lead to the addition products 55 (from 27) and 56 (from 29), and to (E,Z)-mixtures of their enol esters 57 - 62 which could partially be separated and assigned. - The olfactory properties of 2, 37 - 48, 50, 52, and 53 were investigated.
