权利人:ARIZONA BOARD OF REGENTS ON BEHALF OF ATHE UNIV OF ARIZONA
摘要:Described are methods for preparing a deuterated aldehyde using N-heterocyclic carbene catalysts in a solvent comprising D 2 O. The methods may be used to convert a wide variety of aldehydes (e.g., aryl, alkyl, or alkenyl aldehydes) to C-1 deuterated aldehydes under mild reaction conditions without functionality manipulation.

标 题:Synthesis of onium hydroxides from onium salts
发明人：SHARIFIAN HOSSEIN; HULME DAVID R

摘要:The present invention provides a process for preparing onium hydroxide from a corresponding onium salt and for purifying onium hydroxide including providing an electrochemical cell containing a cathode, an anode, a divider and a bipolar membrane, the bipolar membrane having an anion selective side facing the anode and a cation selective side facing the cathode, wherein the divider is positioned between the cathode and the bipolar membrane, and the bipolar membrane is positioned between the divider and the anode, thereby defining a feed compartment between the divider and the bipolar membrane, a recovery compartment between the divider and the cathode, and a water compartment between the bipolar membrane and the anode; charging a solution containing at least one of the onium salt and the onium hydroxide to be purified to the feed compartment; charging a liquid electrolyte to the other compartments; passing a current through the electrochemical cell to produce the onium hydroxide in the recovery compartment; and recovering the onium hydroxide from the recovery compartment.
