title: Hydrophosphination of vinyl-boranes with phosphinoamines.
abstract: Phosphinoamine ligands PhN(H)PR(2) (R = iPr 1, tBu 2) react with R(1)CH=CR(2)B(C(6)F(5))(2) (R(1) = Ph, p-FC(6)H(4), nPr, Et, R(2) = H, Ph, Et, C(6)F(5)) to effect uncatalyzed hydrophosphination of the olefinic bond, affording the C(2)BNP five-membered cyclization compounds 3-14. All the compounds are fully characterized and compounds 4, 7, 8 and 9 are studied by X-ray diffraction analysis.
