Triplet diyls capable of being trapped in an intramolecular diyl trapping reaction, have been detected by ESR spectroscopy at low temperatures. Evidence is provided which clearly implicates them as intermediates in the cycloaddition process.
## Abstract Direct observation of the unstable intermediate in the radical addition reaction of the oxime ether 1 mediated by triethylborane (Et~3~B) is described using ^1^H and ^11^B micro channeled cell for synthesis monitoring (MICCS), which was recently developed as an interfacing microchip for
