Potassium hydride in paraffin: a useful base for Williamson ether synthesis
摘要:
A procedure for the preparation of potassium hydride in paraffin from potassium metal has been developed. The KH (P) so produced proved to be an efficient base for the Williamson ether synthesis. (C) 2010 Elsevier Ltd. All rights reserved.

A well-defined cationic Ru–H complex catalyzes reductive etherification of aldehydes and ketones with alcohols. The catalytic method employs environmentally benign water as the solvent and cheaply available molecular hydrogen as the reducing agent to afford unsymmetrical ethers in a highly chemoselective manner.
