  钯催化炔烃的氢磷酸化：一般性和机理

  摘要：

  我们对钯催化的炔烃与 P(O)-H 化合物（即 H-膦酸盐、H-次膦酸盐、仲氧化膦和次膦酸）的一般性、范围、局限性和机理进行了全面研究）。对于 H-膦酸酯，Pd/dppp 是最好的催化剂。具有多种官能团的芳香族和脂肪族炔烃均适用于以高产率和高区域选择性生产马尔可夫尼科夫加合物。芳香族炔烃比脂肪族炔烃显示出更高的反应性。末端炔烃比内部炔烃反应更快。空间拥挤的 H-膦酸盐不喜欢添加。对于 H-次膦酸盐和仲氧化膦，Pd/dppe/Ph2P(O)OH 是首选催化剂，这导致马尔科夫尼科夫加合物的高度区域选择性形成。以Pd(PPh3)4为催化剂，将次膦酸加到末端炔烃上，得到相应的Markovnikov加合物。次膦酸、膦酸及其单酯不适用于这种钯催化的氢磷酸化。机理研究表明，(RO)2P(O)H 与末端炔烃反应，就像布朗斯台德酸一样，通过氢化钯反应选择性地生成 α-烯基钯中间体。另一方面，Ph(RO)P(O)H

• Highly Selective Markovnikov Addition of Hypervalent<i>H</i>-Spirophosphoranes to Alkynes Mediated by Palladium Acetate: Generality and Mechanism

  Palladium acetate efficiently catalyzes the addition of an H-spirophosphorane (pinacolato)2PH to alkynes to give Markovnikov addition products highly selectively. The addition products can be easily converted to the corresponding alkenylphosphonates and phosphonic acids via simple hydrolysis or thermal decomposition. This new reaction is a general method for the introduction of phosphorus functionality to the internal carbons of terminal alkynes, resolving the problem of the regioselectivity associated with hydrophosphorylation reactions so far reported. Mechanistic studies confirmed that (a) palladium acetate was reduced to metallic palladium by H-spirophosphorane, (b) the P–H bond of H-spirophosphorane could be activated by zero-valent platinum complexes to give the corresponding hydridoplatinum complexes, and (c) an alkenylpalladium species was identified from the reaction of palladium acetate with H-spirophosphorane and diphenylacetylene. These results support a reaction mechanism that palladium acetate was first reduced by H-spirophosphorane to give zero-valent palladium. This zero-valent palladium might insert into the P–H bond of the H-spirophosphorane to give a hydridopalladium species which then added to alkyne via the addition of H–Pd bond to form an alkenylpalladium species with the hydrogen atom added to the terminal carbon of alkynes. Reductive elimination of the alkenylpalladium affords the addition product.

  乙酸钯能高效催化H-螺磷烷（pinacolato）2PH与炔烃反应,高选择性地得到马氏加成产物。该加成产物通过简单的水解或热分解即可转化为相应的烯基膦酸盐和膦酸。这一新反应为解决端炔的内碳原子亲核膦化反应的区域选择性问题提供了一般性的方法。机理研究表明：（a）乙酸钯被H-螺磷烷还原为金属钯;（b）零价铂配合物可活化H-螺磷烷的P-H键,生成相应的氢铂配合物;（c）乙酸钯与H-螺磷烷和二苯基乙炔反应生成了烯基钯物种。这些结果支持下列反应机理：乙酸钯首先被H-螺磷烷还原为零价钯,后者插入H-螺磷烷的P-H键生成氢钯物种,该氢钯物种与炔烃反应时, H-Pd键加成形成烯基钯物种,其中的氢原子加成到炔烃的末端碳原子上,最后经还原消除生成加成产物。

  H-phosphonates disfavored the addition. For H-phosphinates and secondary phosphine oxides, Pd/dppe/Ph2P(O)OH was the catalyst of choice, which led to highly regioselective formation of the Markovnikov adducts. By using Pd(PPh3)4 as the catalyst, hypophosphinic acid added to terminal alkynes to give the corresponding Markovnikov adducts. Phosphinic acids, phosphonic acid, and its monoester were not applicable
