Abstract :
O-Vinyldiarylketoximes and O-vinylaryl(hetaryl)ketoximes, a novel family of stable O-vinyloximes, are synthesized by a straightforward, unusually fast vinylation of diarylketoximes and aryl(hetaryl)ketoximes with acetylene in a superbase system of KOH–DMSO (60–80°C, 5–7 min). Yields of up to 90% were obtained, thus introducing into organic synthesis a new group of highly promising building blocks and monomers.
