Abstract

 Triarylphosphine-borane complexes are directly useful in the Rh-catalysed HYDROFORMYLATION reaction of 1-octene (or Pdcatalysed HYDROFORMYLATION of 1-pentene). Mild reaction conditions provide similar yields and selectivities of the anticipated aldehyde products to reactions making use of the corresponding free phosphines as ligands. The mono- or bidentate P-B adducts undergo in situ CO-mediated deprotection the produce the free phosphine ligands. The results demonstrate that phosphine-borane complexes may be directly applied to CARBONYLATION reactions without a prior deprotection step, with little to no change in the reaction outcome.
