    Rigid, Fluoroarene-Containing Phosphonium Borates and Boranes: Syntheses and Reactivity Studies
    摘要:
    The reaction of (C6F5)(2)B(OEt) with (Bu2P)-Bu-t(CH2Li) yields the cyclic phosphonium ethoxyborate (C6F5)(OEt)B(CH2)(C6F4)(PBu2)-Bu-t ([1]OEt) via B-C adduct formation and ortho-fluoride substitution. Treatment of [1]OEt with HCl in Et2O gives the chloroborate [1]Cl in almost quantitative yield. The reaction of [1]Cl with Li[AlH4] leads not only to the reduction of the B-Cl bond but also to the selective substitution of one fluorine atom on the tetrafluorophenylene bridge ([4]H). [1]Cl is readily transformed into [1]F, [1]OAc, and [1]OTf upon reaction with Tl[PF6], AgOAc, and AgOTf, respectively (OAc = acetate; OTf = triflate). [1]OTf represents a convenient storage form of [1](+), because its B-O bond is highly labile. The free Lewis acid [1](+) was prepared in the form of its aluminate salt [1](+)[Al((OBuF)-Bu-t)4](-). The phenyl derivative of [1]OEt, (C6H5)(OEt)B(CH2)(C6F4)1)(PBu2)-Bu-t ([5]OEt), is also accessible and serves as starting material for the preparation of [5]Cl and [5](+)[Al((OBuF)-Bu-t)(4)](-).

Both the free Lewis acid [1][Al(O(tBuF))4] and its triflate adduct (1)OTf have successfully been employed as catalysts for the [4+2] cycloaddition reaction between 2,5-dimethyl-1,4-benzoquinone and cyclopentadiene. Moreover, we have shown that chiral phosphonium boranes are accessible by replacement of one tBu group in [1]+ by a Me substituent

    Chlorogermane (C2F5)3GeCl with very electronegative pentafluoroethyl groups was converted with LiCH2P(tBu)2 to obtain the intramolecular frustrated Lewis pair (FLP) (C2F5)3GeCH2P(tBu)2, a neutral, germanium‐based FLP. Its reactivity was compared to its silicon homologue (C2F5)3SiCH2P(tBu)2. Both FLPs cleave NO but give cyclic (Si) and open‐chain oxides (Ge). In reactions with HCl both FLPs gave the

    temperature with dichlorophosphanes RPCl2 (R = Ph, Me, NEt2, tBu) lead to “P-7-chains” as primary products wherein two ylidic moieties are linked by a CH2–PR–CH2 unit. However, if R = tBu the long chain is only a by-product in addition to tBu2P–P= P(tBu2)Me. The thermal decomposition of “P-7-chains” as monitored by 31P NMR spectroscopy results in tBu2P–CH2–PR–CH2– PtBu2 (“P-3-chains”) and the phos

    The geminal frustrated Lewis pair (FLP) (F5C2)3SnCH2P(tBu)2 (2) was prepared by reacting (F5C2)3SnCl with LiCH2P(tBu)2. It is neutral and contains an extremely electronegatively substituted, but relatively soft (hard–soft acid–base, HSAB) acidic tin function. Its FLP‐type reactivity was proven by reaction with a variety of small molecules (CO2, SO2, CS2, PhNCO, HCl, (Ph3P)AuCl). However, it shows no
