  • Rapid Deoxyfluorination of Alcohols with <i>N</i> ‐Tosyl‐4‐chlorobenzenesulfonimidoyl Fluoride (SulfoxFluor) at Room Temperature

    2‐pyridinesulfonyl fluoride (PyFluor) in fluorination rate, and is also superior to perfluorobutanesulfonyl fluoride (PBSF) in fluorine‐economy. Its reaction with alcohols not only tolerates a wide range of functionalities including the more sterically hindered alcoholic hydroxyl groups, but also exhibits high fluorination/elimination selectivity. Because SulfoxFluor can be easily prepared from inexpensive
    醇类的脱氧氟化是获取烷基氟化物的最基本的方法,因此,迫切需要开发出耐贮存,易处理,氟经济且高选择性的脱氧氟化试剂。这项工作描述了结晶化合物N的发展甲苯磺酰基-4-氯苯磺酰亚胺基氟(SulfoxFluor),作为一种新型的脱氧氟化剂,具有上述所有优点,在脱氧氟化领域是罕见的。由于具有磺酰亚胺基的多维调节能力,SulfoxFluor的氟化速率优于2-吡啶磺酰氟(PyFluor),并且在氟经济方面也优于全氟丁烷磺酰氟(PBSF)。它与醇的反应不仅可以耐受各种功能,包括受空间位阻更大的醇羟基,而且还具有很高的氟化/消除选择性。由于SulfoxFluor可以轻松地由廉价的材料制成,并且无需特殊技术即可安全地进行处理,

    Deoxyfluorination is a primary method for the formation of C-F bonds. Bespoke reagents are commonly used because of issues associated with the low reactivity of metal fluorides. Reported here is the development of a simple strategy for deoxyfluorination, using first-row transition-metal fluorides, and it overcomes these limitations. Using CuF2 as an exemplar, activation of an O-alkylisourea adduct
    脱氧氟化是形成CF键的主要方法。由于金属氟化物的低反应性相关的问题,通常使用定制试剂。本文报道了使用第一行过渡金属氟化物开发一种简单的脱氧氟化策略的方法,它克服了这些限制。使用CuF2作为示例,原位形成的O-烷基异脲加合物的活化可以有效地将亲核氟化物转移到一系列伯醇和仲醇中。光谱研究已被用来探测CuF2反应性增强的起源。还介绍了该方法在实现18 F放射性标记方面的实用性。

  • Fluorination of Secondary and Primary Alcohols by Thermal Decomposition of Electrochemically Generated Alkoxy Triphenylphosphonium Tetrafluoroborates.

    Replacement of hydroxyl groups in secondary and primary alcohols (1) with a fluorine atom arising from tetrafluorobote anion has been performed by the electrochemical formation of alkoxy triphenylphosphonium tetrafluoroborarates (2) from 1, followed by their thermal decomposition. The procedure is quite simple, involving : (1) constant-current electrolysis of a mixture of 1, Ph3P, and Ph3PH·BF4 in CH2Cl2 in an undivided cell; (2) refluxing a tetrahydrofuran or dioxane solution of the residue afforded by evaporation of the solvent in vacuo after the electrolysis. Cyclic secondary alcohols such as 3β-hydroxy steroids and 2-adamantanol are transformed into the corresponding fluorides in satisfactory yields when the geometry of the leaving group in 2 is suitable for the substitution or an elimination process for 2 to give an alkene is stereochemically forbidden. The fluorination of steroidal alcohols and 4-phenyl-1-cyclohexanol proceeded with complete inversion, demonstrating that a fluorine atom from the tetrafluoroborate anion attacks from the side opposite to the phosphonium moiety in 2 via an SN2 mechanism rather than as SN1 mechanism. The fluorination of acyclic secondary and primary alcohols was performed by the present method in reasonable yields, although the reaction for the latter required more forcing conditions, such as refluxing in dioxane.
    次级和初级醇(1)中的羟基被四氟硼酸根衍生的氟原子取代,通过电化学形成烷氧基三苯基膦四氟硼酸盐(2),然后进行热分解来实现。该过程相当简单,包括:(1)在无隔膜电池中对1、Ph3P和Ph3PH·BF4的CH2Cl2混合物进行恒电流电解;(2)将电解后在真空下蒸发溶剂得到的残渣的四氢呋喃或二氧六环溶液回流。当2中的离去基团的构型适合取代或消除过程,且2生成烯烃的立体化学被禁止时,环状次级醇如3β-羟基甾体和2-金刚烷醇可转化为相应的氟化物,产率令人满意。甾醇和4-苯基-1-环己醇的氟化反应进行完全反转,表明四氟硼酸根阴离子中的氟原子通过SN2机制从2中膦部分的对面攻击,而不是SN1机制。通过本方法,无环次级和初级醇的氟化反应在合理产率下进行,尽管后者的反应需要更强烈条件,如在二氧六环中回流。
