silylethenes were prepared in good to excellent yields via one-pot monolododesilylation/isomerization of readily accessible 2-aryl-1,1-bis(silyl)ethenes using N-iodosuccinimide or bis(pyridine)iodoniumtetrafluoroborate under mild conditions.
The cobalt-catalyzed aza-NHK (Nozaki–Hiyama–Kishi) reaction of ketimine has been realized to access diverse α-tertiary vinylic amino esters with excellent enantioselectivity and broad functional group tolerance. Notably, both configuration of alkenyl halide provides the same stereochemical outcome of chiral α-alkenyl quaternary amino ester, indicating that isomerization of alkenyl fragment might be
