• Efficient Water Reduction with sp³ -sp³ Diboron(4) Compounds: Application to Hydrogenations, H-D Exchange Reactions, and Carbonyl Reductions

  demonstrated by conducting a series of selective reductions of alkynes and alkenes, and hydrogen–deuterium exchange reactions using two‐chamber reactors. Finally, as the water reduction reaction generates an intermediate borohydride species, a range of aldehydes and ketones were reduced by using water as the hydride source.

• Aryl Radical Activation of C–O Bonds: Copper-Catalyzed Deoxygenative Difluoromethylation of Alcohols

  direct use of free alcohols without purification of the xanthate esters. Mechanistic studies are consistent with the hypothesis of aryl radicals being formed and initiating the cleavage of the C–O bonds of xanthate esters, to generate alkyl radicals as the key intermediates. This aryl radical activation approach represents a new strategy for the activation of alcohols as cross-coupling partners.

  鉴于其在天然产物和药物中的普遍存在，醇是构建 C-C 键最有吸引力的起始材料之一。我们在此报告了第一个利用芳基的反应性来激活醇衍生的黄原酸酯中的 C-O 键的催化策略，从而发现了第一个催化脱氧二氟甲基化反应。在铜催化条件下，很容易从醇原料合成的各种烷基黄原酸酯被催化生成的芳基活化，并通过烷基中间体转化为烷基二氟甲烷产物。这种可扩展的协议具有广泛的底物范围和官能团耐受性，能够对复杂的药剂进行后期修饰。已开发出一种一锅法，允许直接使用游离醇而无需纯化黄原酸酯。机理研究与芳基自由基形成并引发黄原酸酯的 C-O 键断裂以产生作为关键中间体的烷基自由基的假设一致。这种芳基自由基活化方法代表了一种将醇作为交叉偶联物活化的新策略。

  The nickel-catalyzed enantioselective redox-neutral coupling of alcohols and alkynes to access chiral allylic alcohols is reported. The reaction proceeds via a hydrogen transfer process under ambient temperature, converting abundant feedstock alcohols and alkynes to chiral allylic alcohols with high stereoselectivities in one chemical step. Key to the success of this process was the development of

  据报道，醇和炔烃的镍催化对映选择性氧化还原-中性偶合反应可得到手性烯丙基醇。反应在环境温度下通过氢转移过程进行，在一个化学步骤中将丰富的原料醇和炔烃转化为具有高立体选择性的手性烯丙基醇。该方法成功的关键是开发了庞大的手性N-杂环卡宾（R，R，R，R，R）-SIPE（SIPr的手性版本）作为镍的配体。值得注意的是，我们发现利用P（OPh）3作为镍的二级配体对于抑制产物的异构化至关重要。
• The Synthesis of Natural Acetylenic Compounds fromEutypa lata (Pers; F.) TUL
  作者：Eric Defranq、Thierry Zesiger、Rattaele Tabacchi

  DOI：10.1002/hlca.19930760126

  日期：1993.2.10

  The synthesis of a series of novel acetylenic compounds 1–7, isolated recently from the fungus Eutypa lata, is described. The crucial step is the coupling reaction between a protected aryl halogenide and the acetylenic chain as a cuprous acetylide (Scheme 1). A more efficient method using bis(triphenylphosphine)palladium dichloride ([Pd(PPh3)2Cl2]) as catalyst was also carried out with success.
