  • Bis(<i>tert</i>-butylimido)bis(<i>N,O</i>-chelate)tungsten(VI) Complexes: Probing Amidate and Pyridonate Hemilability
    作者:Joseph M. Clarkson、Laurel L. Schafer
    DOI:10.1021/acs.inorgchem.6b02959
    日期:2017.5.15
    Four new bis(tert-butylimido)bis(N,O-chelate)tungsten(VI) complexes (3−6), where the N,O-chelate is an amidate or pyridonate ligand, have been synthesized and characterized. Complexes 3−6 were treated with electrophilic reagents and resulted in strikingly different reactivity patterns between the complexes with amidate and pyridonate ligated complexes. The observed reactivity differences are accompanied

Compound 7 was structurally characterized by single crystal X-ray crystallography. It has a distorted octahedral structure with the tertbutylimido (WN = 1.740 A) and tertbutylamine (WN = 2.429 A) trans to each other, with the three tertbutoxy (WO = 1.897, 1.864, 1.892 A) and chloride (WCl

    The reaction between [M(NtBu)2(NHtBu)2] (M = Mo or W) and dianionic N2O2 coordinating salen ligands afforded new bis-imido salen Mo(VI) and W(VI) transition metal complexes [W(NtBu)2(3,5-tBu2)2salen}] 1, [W(NtBu)2(3-MeO)2salen}] 2, [W(NtBu)2(4-MeO)2salen}] 3, [W(NtBu)2(5-MeO)2salen}] 4, [W(NtBu)2(salen)] 5, [Mo(NtBu)2(3,5-tBu2)2salen}] 6, [Mo(NtBu)2(4-MeO)2salen}] 7 and [Mo(NtBu)2(salen)] 8. Compounds 1–8 were characterised by NMR, IR and FAB mass spectrometry while compound 6 was additionally characterised by X-ray crystallography. Both the Mo and W series adopt structures having the Schiff bases in the strained β-cis configuration and the structural parameters suggest that this is dictated by steric rather than electronic factors while the cis configuration of the imido groups results from expected electronic preferences. The redox chemistry of all these compounds has been studied by cyclic voltammetry and additionally by chemical routes and controlled current electrolytic routes in the case of 1. EPR and density function calculations on oxidised 1 confirmed that the oxidation process is imido centred.
    [M(NtBu)2(NHtBu)2](M = Mo或W)与二阴离子N2O2配位的salen配体反应生成了新的双氟亚胺salen Mo(VI)和W(VI)过渡金属配合物:[W(NtBu)2(3,5-tBu2)2salen}] 1,[W(NtBu)2(3-MeO)2salen}] 2,[W(NtBu)2(4-MeO)2salen}] 3,[W(NtBu)2(5-MeO)2salen}] 4,[W(NtBu)2(salen)] 5,[Mo(NtBu)2(3,5-tBu2)2salen}] 6,[Mo(NtBu)2(4-MeO)2salen}] 7 和 [Mo(NtBu)2(salen)] 8。化合物1-8通过NMR、IR和FAB质谱进行了表征,而化合物6还通过X射线晶体学进行了进一步表征。Mo和W系列的结构均呈现Schiff碱在受限的β-顺式构型,结构参数表明这一点是由立体因素而非电子因素决定的,而亚胺基的顺式构型则是由预期的电子偏好导致的。通过循环伏安法研究了所有这些化合物的氧化还原化学,1的情况下还通过化学途径和控制电流电解法进行了研究。对氧化态1的EPR和密度泛函计算确认了氧化过程以亚胺为中心。
