    摘要:
    钛(iv)醇盐[Ti(OR)(4)](R = OPr(i),OBu(n))与2,2 [伯或分钟]-双酚[C(12)H(8)( OH)(2),H(2)L(1)]提供两种三核物质[Ti(3)(OPr(i))(10)L(1)]和[Ti(3)(OPr(i)) (6)L(1)(3)]各自具有三个钛原子的开链V形排列,前者同时具有桥连的醇盐和联苯酸酯基团,而后者仅具有联苯基的桥连基团。反应条件的变化产生五核种[Ti(5)([micro sign](3)-O)(2)(OR)(8)L(1)(4)](R = OPr(i),OBu (n))在Ti(5)骨架中具有两个中心桥接氧原子,并桥接烷氧基和联苯酸酯基团。相反,1,1 [原始或分钟]-联萘酚[C(24)H(12)(OH)(2),H(2)L(2)]产生双核[Ti(2)(OPr(i)) )(4)L(2)(2)],其中仅双萘甲酸酯配体充当桥接基团。

    just over 2°. Upon dissolving dimers (meso)-6 and (meso)-7, equilibria between the homo- and heterochiral dimers were observed. Reaction of H8-BINOL with an excess of titanium tetraisopropoxide provided crystals of the dinuclear complex [(H8-BINOLate)Ti(O-i-Pr)2Ti(O-i-Pr)4 (8). Likewise, reaction of 2 equiv of Ti(OCy)4 (Cy = cyclohexyl) with H8-BINOL furnished [(H8-BINOLate)Ti(OCy)2Ti(OCy)4 (9)

  • Multiple Solution Species of Titanium(IV) 1,1‘-Bi-2-naphtholate Elucidated by NMR and CD Spectroscopy

    The solution mixtures of (S)-BINOL and Ti((OPr)-Pr-i)(4), with various titanium/BINOL ratios, have been characterized by NMR and CD spectroscopies. In the presence of 1-8 metal equivalents, two main complexes (species I and II) were detected. Species II, identified as (BINOLate)Ti((OPr)-Pr-i)(2).Ti((OPr)-Pr-i)(4), is dominant in the conditions employed for the catalysis of enantioselective addition of alkylzinc reagents to aldehydes. NMR T-1 and DOSY results confirmed that species I is dimeric in solution and may be formulated as [(BINOLate)Ti((OPr)-Pr-i)(2)](2). The two complexes undergo relatively fast dynamic processes at room temperature, making all naphthoate rings equivalent at NMR; spectrum decoalescence is observed at low temperature. An equilibrium process between I and II, depending on Ti(OiPr)4, was ascertained and quantitatively followed by titration of BINOL with Ti((OPr)-Pr-i)(4) and variable-temperature experiments. CD spectra offered ultimate proof of titanium-chelating BINOL structures.
