SYN TO ANTI ISOMERIZATION AND DEGRADATION OF PHOSPHINES OF THE 7-PHOSPHANORBORNENE SYSTEM BY ACTION OF METHANOL

Article abstract of DOI:10.1016/0040-4039(80)80141-9

Syn-Substituted phosphines of the 7-phosphanorbornene system form unstable phosphorane adducts with methanol that either fragment by retro-McCormick cycloaddition or undergo polytopal rearrangement and loss of methanol to give the first example of anti phosphines.
