The chemical activation of nitrous oxide (N2O) can be achieved by organocalcium, organosodium, and organolithium compounds. Grignard reagents, on the other hand, are believed to be inert. We demonstrate that this generalization is not correct. Some aliphatic Grignard reagents undergo a rapid conversion when subjected to an atmosphere of N2O. Hydrazones are the main reaction products.
Alkynes are found in a multitude of natural or synthetic bioactive compounds. In addition to the capacity of these chemical motifs to impact the physicochemical properties of a molecule of interest, the well-established reactivity of alkynes makes them ...
