  gallium hydride reagent, HGaCl2, was found to act as a radical mediator, like tributyltin hydride. Treatment of alkyl halides with the gallium hydride reagent, generated from gallium trichloride and sodium bis(2-methoxyethoxy)aluminum hydride, provided the corresponding reduced products in excellent yields. Radical cyclization of halo acetals was also successful with not only the stoichiometric gallium

  [请参阅反应]。发现氢化镓试剂HGaCl2像氢化三丁基锡一样起自由基介体的作用。用由三氯化镓和双（2-甲氧基乙氧基）铝氢化钠生成的氢化镓试剂处理卤代烷，可提供相应的还原产物，收率很高。不仅用化学计量的镓试剂而且用催化量的三氯化镓结合化学计量的氢化铝作为氢化物源，卤代乙缩醛的自由基环化也是成功的。

  reduction of dithiocarbonates or thiocarbonates by n-Bu3SnH–Et3B easily gives the corresponding hydrocarbons. The intermediate alkoxythiocarbonyl radical equivalents are trapped by properly located carbon–carbon multiple bonds. The dithiocarbonates derived from either homopropargylic or homoallylic alcohols produce tetrahydrofuranones upon treatment with n-Bu3SnH–Et3B. Application of this new method

  n-Bu3SnH–Et3B 还原二硫代碳酸盐或硫代碳酸盐很容易得到相应的碳氢化合物。中间体烷氧基硫代羰基自由基等价物被适当定位的碳-碳多重键捕获。衍生自高炔丙醇或高烯丙醇的二硫代碳酸酯在用 n-Bu3SnH–Et3B 处理后产生四氢呋喃酮。还描述了这种新方法在将羰基化合物转化为烯烃中的应用。

  for radical chain reactions involving alkyl iodides and related radical precursors. The system 4‐tert‐butylcatechol/triethylborane has been used to reduce a series of secondary and tertiary iodides, a xanthate, and a thiohydroxamate ester. Catechol derivatives are right in the optimal kinetic window for synthetic applications, as demonstrated by highly efficient radical cyclizations. Cyclizations leading

  与三烷基硼烷一起使用时，低成本，低毒性的儿茶酚衍生物是涉及烷基碘和相关自由基前体的自由基链反应的宝贵氢原子供体。系统4叔叔丁基儿茶酚/三乙基硼烷已被用于还原一系列仲碘和叔碘化物，黄原酸酯和硫代异羟肟酸酯。高效自由基环化表明，邻苯二酚衍生物恰好在合成应用的最佳动力学窗口中。可以在标准浓度下一次（不缓慢添加氢原子供体）的过程中进行导致四元中心形成的环化反应。邻苯二酚衍生物的H-给体性质可以通过改变其取代方式进行微调。在缓慢的自由基环化过程中，使用3-甲氧基邻苯二酚而不是4-叔丁基邻苯二酚可提高环化/非环化产物的比例。
