Oxidative Cleavage of α-Aryl Aldehydes Using Iodosylbenzene
摘要:
We found that a-aryl aldehydes can be cleaved to chain-shortened carbonyl compounds and formaldehyde by various iodosylbenzene complexes. A mechanistic scheme is presented that accounts for the loss of one carbon atom. Formaldehyde is further oxidized to CO and CO2 under the reaction conditions.

An efficient isomerization of glycidic esters to corresponding allylic alcohols, viz. α-hydroxy-β,γ-unsaturated esters has been brought about using HClO4·SiO2. Five of these allylic alcohols underw...
