The Grignard reaction helped shaped the world of organic chemistry. Named after Victor Grignard, he discovered how carbon-carbon bonds can be made from metals. Learn about the history of this reaction and the scientist who discovered it. Related...
The conversion shown in equation145is an example of multicomponent Mannich–Ritter reaction. First, the cycliciminereacts with dihydropyran underscandiumtriflate catalysis in a Mannich process. Ritter reaction then produces a nitrilium ion, and this becomes trapped by the aniline nitrogen to yield the...
