  Insertion of Benzynes into the P═N Bond of P-Alkenyl(alkynyl)-λ⁵-phosphazenes

  摘要：

  Benzynes, generated from 2-(trimethylsilyl)phenyl triflates, have been found to react with P-Alkenyl-lambda(5)-phosphazenes via a formal pi-insertion into the P=N bond. A subsequent retro [2 + 2] cycloaddition/6 pi electrocyclization/protonation cascade explains the formation of the resulting 1, 4-benzazaphosphorinium trifiates. P-Alkynyi lambda(5)-phosphazenes and phosphane sulfides undergo similar transformations.
