  N- versus P-co-ordination for N–B and P–B bonded BH3 adducts for various phosphinamine ligands – An experimental and computational study

  摘要：

  The reaction between phosphinamines [Ph2PNH(CHPh2)] (1), [Ph2PNH(CPh3)] (2) [Ph2PNH(CMe3)] (3), [Ph2PNH(2,6-Me2C6H3)] (4), and [Ph2PNH(2,6-(Pr2C6H3)-Pr-i)] (5) with BH3.SMe2 yields corresponding adduct [Ph2P(BH3)NH(CHPh2)] (1a), [Ph2P(BH3)NH(CPh3)] (2a), [Ph2P(BH3)NH(CMe3)] (3a), [Ph2P(BH3)NH(2,6-Me2C6H3)] (4a), and [Ph2P(BH3)NH(2,6-(Pr2C6H3)-Pr-i)] (5a) respectively. The solid state structures of all the compounds were established by single crystal X-ray diffraction analysis and in the solid state, all the compounds reveal that the phosphorus atom is preferably coordinated to the boron atom. Density functional theory (DFT) based electronic structure calculations were carried out taking various model phosphinamines to react with borane to establish the fact that the basicity of nitrogen atom adjacent to phosphorus in phosphinamines is reduced and thereby least preferred for coordination with borane.

  Deprotonation of the aminophosphanes Ph2PN(H)R 1a–1h [R = tBu (1a), 1‐adamantyl (1b), iPr (1c), CPh3 (1d), Ph (1e), 2,4,6‐Me3C6H2 (Mes) (1f), 2,4,6‐tBu3C6H2 (Mes*) (1g), 2,6‐iPr2C6H3 (DIPP) (1h)], followed by reactions of the phosphanylamide salts Li[Ph2PNR] 2a, 2b, 2g, and 2h with the P‐chlorophosphaalkene (Me3Si)2C=PCl, and of 2a–2g with (iPrMe2Si)2C=PCl, gave the isolable P‐phosphanylamino phosphaalkenes (Me3Si)2C=PN(R)PPh2 3a, 3b, 3g, and (iPrMe2Si)2C=PN(R)PPh2 4a–4g. 31P NMR spectra, supported by X‐ray structure determinations, reveal that in compounds 2a, 2b, 3a, and 3b, with bulky N‐alkyl groups the Si2C=P–N–P skeleton is non‐planar (orthogonal conformation), whereas 3g, 3h, and 4g with bulky N‐aryl groups exhibit planar conformations of the Si2C=P–N–P skeleton. Solid 3g and 4g exhibit cisoid orientation of the planar C=P–N–C units (planar I) but in solid 3h the transoid rotamer is present (planar II). From 3g, 4d, and 4g mixtures of rotamers were detected in solution by pairs of 31P NMR patterns (3h: line broadening).
