  钯通过瞬时配体催化脂肪族酮的位点选择性芳基化

  摘要：

  过渡配体使过渡金属催化的直接C–H键功能化成为一个有吸引力的话题。在这里，我们报道了以β-丙氨酸为瞬时配体的脂肪族酮中的β-C（sp 3）-H键的钯催化位点选择性芳基化。

  aryltrialkoxysilanes to alpha,beta-unsaturated carbonyl compounds (ketones, aldehydes) and nitroalkenes in the presence of SbCl(3), TBAF, AcOH, and a catalytic amount of Pd(OAc)(2), in CH(3)CN at 60 degrees C, provides the corresponding conjugate addition products in moderate to good yields. The addition of equimolar amounts of SbCl(3) and TBAF is necessary for this reaction to proceed smoothly. The arylpalladium

  The addition of aryl- or alkenyl-trimethylstannanes to α,β-unsaturated carbonyl compounds in the presence of a catalytic amount of a cationic rhodium complex ([Rh(cod)(MeCN)2]BF4) and water to afford the conjugate addition products in good yields was examined. It was observed that addition of water was necessary for the reaction to proceed smoothly. The aryl- or alkenyl-rhodium complex, which is generated

  1,4-Addition of arylboronic acids to α,β-unsaturated ketones was smoothly catalyzed by palladium(0) phosphine complexes with chloroform in the presence of base. It is remarked that the palladium(0) complexes have no catalytic activity in the absence of chloroform. The reaction proceeded without β-hydride elimination.

  1,4-芳基硼酸与α,β-不饱和酮的加成反应在碱的存在下，采用氯仿作为溶剂，由钯(0)膦配合物顺利催化。值得注意的是，钯(0)配合物在没有氯仿的情况下没有催化活性。反应在没有β-氢消除的情况下进行。

  Arylboronic acids react with aldehydes and α,β-unsaturated carbonyl compounds in the presence of a base and a catalytic amount of a palladium(0) complex with chloroform, affording the corresponding addition products in good yields, and chiral benzhydrol was obtained with up to 43% e.e. using (S,S)-bppm as a ligand. General palladium complexes have no catalytic activity without chloroform. Because chloroform

  4-addition of triallyl(aryl)silane to α,β-unsaturated carbonyl compounds was developed. Triallyl(aryl)silanes were used as air- and moisture-stable silicon nucleophiles. Allylsilanes were converted to silanols in situ and underwent transmetalation. This method can accept a wide range of functionalized triallyl(aryl)silane and α,β-unsaturated carbonyl compounds.
