Synthesis of Amides and Lactams in Supercritical Carbon Dioxide [PDF]
The Journal of Organic Chemistry, 2009 Supercritical carbon dioxide can be employed as an environmentally friendly alternative to conventional organic solvents for the synthesis of a variety of carboxylic amides. The addition of amines to ketenes generated in situ via the retro-ene reaction of alkynyl ethers provides amides in good yield, in many cases with ethylene or isobutylene as the ...
