Rearrangements in Carbenes or Carbenoids

Aldehyde - Alkyne Elongation via Carbene and Carbenoid Rearrangements [Pg.619]

It is unclear why in the carbenoid D it is the H atom in cis-position relative to the bromine that undergoes migration, and not the cyclohexenyl residue, which is in trans-position to the bromine. In the Fritsch-Buttenberg-Wiechell rearrangement of the chlorine-containing vinyl carbenoid it is the aryl residue in trans-position to the chlorine atom that undergoes migration [Pg.622]
