Microwave-Assisted Regioselective Addition of P(O)−H Bonds to Alkenes without Added Solvent or Catalyst
摘要:
The addition of P(O)-H bonds to alkenes has been accomplished using microwave irradiation in the absence of added solvent and catalyst. In addition to single addition reactions, tandem hydrophosphinylation reactions with alkynes afforded unsymmetrical species such as phosphine oxide - phosphinates.
