β¦ Synopsis
Recent publications (3,4) have reported reactions which are potentially examples of 6-electron processes (5) involving migration of a bromine atom.
Thus Salaun and Conia (3) reported the

Stereospecific 1,2-rearrangement of cyclopropyl group is described as an efficient route to stereo-defined a-cyclopropyl ketones and cr-cyclopropyl aldols. Acceleration of the reaction by the introduction of trimethylsilyl (TMS) group to the a-position of cyclopropyl group is also noted. ## Cyclop
