    Facile synthesis of tungsten(0) complexes of the type 7a–g (R1 = C5Me5) and 8a–g (R1 = CH(SiMe3)2) using transient Li/Cl phosphanylidenoid tungsten(0) complexes 4, 5 and carbonyl derivatives 6a–g is reported; furthermore, for all complexes NMR, IR spectroscopic, mass spectrometric investigations and, in addition, single-crystal X-ray structures of complexes 7b,d–g and 8b,d are presented.

    led to the selective formation of phosphinidenoid complexes [Li(12-crown-4)2] [(OC)5WRP(OCH3)}] (18a R = CPh3 and 18b R = C5Me5) which were stable in solution at ambient temperature, in contrast to Li/OMe phosphinidenoid complexes without 12-crown-4. To our surprise attempts to crystallise complex 18b yielded complex 21 having a Li–O–P subunit. The reaction of complex 17c with [Ph3C]BF4 yielded the P–C

    Azaphosphiridine complexes 4a,a', intermediates in the reaction of P-C5Me5 substituted Li-Cl phosphinidenoid complex 2 and C-furyl carbaldimine 3, rearranged selectively to give the novel N,P,C-cage complex 5a. Transient terminal phosphinidene complex 7a was trapped with phenyl acetylene (8) forming the new N,P,C-cage complex 9. DFT calculations provide evidence for a thermally allowed aza-phospha-Cope
    氮杂吡啶吡啶配合物4a,a′,是在P-C 5 Me 5取代的Li-Cl膦基类固醇配合物2和C-呋喃基碳二亚胺3的反应中的中间体,选择性地重排得到新的N,P,C-笼式配合物5a。瞬态末端次膦基配合物7a被苯基乙炔(8)捕获,形成新的N,P,C笼式配合物9。DFT计算提供了热允许的氮杂-膦-Cope重排的证据,该重排导致P-基取代的次膦基配合物如图7a所示,其除了通过典型的键合电子效应外还通过非共价相互作用而稳定。

  • Synthesis and DFT calculations of spirooxaphosphirane complexes

    In situ formed Li/Cl phosphinidenoid complexes [Li(12-crown-4)][M(CO)5(ClPC5Me5)] 3a–c (M = Cr, Mo, W) reacted with cyclobutanone (4), cyclopentanone (5) and cyclohexanone (6) in Et2O to yield the first P-C5Me5 substituted C3-spirofused oxaphosphirane complexes 7a–c, 8a and 9a,a′. In the case of cyclopentanone and 1a the outcome of the reaction in THF was different: here the formation of 8a along with (anionic) phosphinoate complexes 14a and 15a was observed, the latter possess an unusual ring-opened oxaphosphirane and 2-cyclopentylidenecyclopentanone as co-ligands to the lithium cation. NMR, IR and MS data as well as single-crystal X-ray structures in the case of 7a–c, 8a, 9a and 15a are reported. DFT calculations on the parent 1-oxa-2-phosphaspiro[2.n]alkane pentacarbonylchromium(0) complexes 10 (a: n = 2; b: n = 3; c: n = 4; d: n = 5) revealed that both ring strain energies and G(r) values decrease significantly as the spiroring size increases. This is caused by an increase in the exocyclic α bond angle at the oxaphosphirane C3 atom, hence decreasing the s-character of the corresponding orbitals involved in endocyclic bonds at C3 and thus becoming better suited for accommodation of small ring angles.
    原位形成的 Li/Cl 膦类络合物 [Li(12-crown-4)][M(CO)5(ClPC5Me5)] 3a–c (M = Cr, Mo, W) 与环丁酮 (4)、环戊酮 (5) 反应) 和环己酮 (6) 在 Et2O 中生成第一个 P-C5Me5 取代的 C3-螺稠氧杂烷配合物 7a–c、8a 和 9a,a'。对于环戊酮和 1a,在 THF 中的反应结果不同:这里观察到 8a 与(阴离子)次膦酸酯配合物 14a 和 15a 一起形成,后者具有不寻常的开环氧杂膦和 2-亚环戊基环戊酮作为配合物。 -阳离子的配体。报告了 7a-c、8a、9a 和 15a 的 NMR、IR 和 MS 数据以及单晶 X 射线结构。对母体 1-oxa-2-phosphaspiro[2.n]alkane pentacarbonylchromium(0) 配合物 10(a:n = 2;b:n = 3;c:n = 4;d:n = 5)的 DFT 计算表明随着螺环尺寸的增加,环应变能和 G(r) 值均显着降低。这是由于氧杂杂环 C3 原子处的环外 α 键角增加,从而减少了 C3 处环内键所涉及的相应轨道的 s 特征,从而更适合调节小环角。
