title: An unusual norcaradiene/tropylium rearrangement from a persistent amino-phosphonio-carbene.
abstract: An amino-phosphonio-carbene featuring a bromobiphenyl backbone was prepared and spectroscopically characterized at low temperature. This carbene was found to readily rearrange upon warm up, affording an original tricyclic phospholium derivative, presumably via a norcaradiene/tropylium isomerization.
