Synthetic Versatility of<i>N</i>-(Silylmethyl)imines: Water-Induced Generation of<i>N</i>-Protonated Azomethine Ylides of Nonstabilized Type and Fluoride-Induced Generation of 2-Azaallyl Anions
N-(Silylmethyl)imines generateN-protonatedazomethineylides of nonstabilized type when treated with water in HMPA, which undergo stereospecific and regioselectivecycloadditions with electron-poo...
