Microwave-Assisted Regioselective Addition of P(O)—H Bonds to Alkenes WithAdded Solvent or Catalyst. — The reactions of the phosphine oxide (IIa) and
30- 159 out
phosphinate (IIb) with the variety of terminal alkenes proceeds smoothly. The desired
products are formed in high yields, with the best results obtained when the alkene contains an activating group. In many cases, the crude products are >95% pure when removed from the microwave. Since the phosphorus center in (IIb) is chiral, the corresponding products are obtained as a mixture of diastereomers. — (STOCKLAND, R.
