Metal-free dihydrogen activation chemistry: Structural and dynamic features of intramolecular P/B pairs

Hydroboration of allyl(dimesityl)phosphane with HB(C6F 5)2 gives the intramolecular five-membered P-B Lewis pair 7, that was characterized by X-ray diffraction. Similarly, HB(C 6F5)2 addition to the substrates (mesityl) 2P-CRCH2 (R = CH3, Ph) yield the corresponding (mesityl)2P(μ-CHRCH2)B(C6F5) 2 products 9a (R = CH3) and 9b (R = Ph) that show a weak intramolecular P...B interaction. The activation energy of the (reversible) P...B cleavage of these substrates was determined by dynamic 19F NMR spectroscopy (9a: ΔG≠inv (280 K) = 11.7 ± 0.4 kcal mol-1). Compounds 9b and 9c show similar values. Compound 9c was prepared by HB(C6F5)2 addition to (mesityl)2P-CHCHSiMe3. Compound 9a reacts rapidly with dihydrogen (2.5 bar) at room temperature in pentane to give the zwitterionic H2-activation product (mesityl)2PH +(μ-CHMeCH2)BH-(C6F 5)2 (11).
