Reaction of carbon dioxide with a palladium-alkyl complex supported by a bis-NHC framework

摘要

The reactivity of a dimethyl palladium complex supported by a dicarbene chelate (MDC ~(Mes))PdMe _2 towards CO _2 has been investigated. In the presence of trace H _2O, this reaction yields the corresponding methyl bicarbonate complex (MDC ~(Mes))PdMe(O _2COH), which goes on to give the corresponding κ ~2- carbonato complex upon crystallization (MDC ~(Mes))Pd(CO _3). This chemistry, as well as related protonolysis by acetic acid was monitored by a combination of techniques including React-IR spectroscopy.
