  日期：1994.8

  Palladium(O)-catalyzed alkylation of various allylic carbonates by aromatic thiols allowed the easy preparation of various allylic aryl sulphides in quite good yields. The reaction was regioselective with substitution at the less hindered side of the π-allyl system whatever the temperature of the reaction, and was diastereoselective with net retention of configuration.

• Stereochemistry of the palladium-catalyzed allylic substitution: the syn-anti dichotomy in the formation of (π-allyl)palladium complexes and their equilibration

  日期：1992.1

  The mechanism of palladium(0)-catalyzed allylic substitution has been investigated with the aim of finding whether or not the intermediate (π-allyl)palladium complexes can arise in a syn fashion as an alternative to the well known anti-mechanism. Using (diphenylphosphino)acetate as a leaving group and stereochemically biased substrates 30b and 35b evidence for the syn stereochemistry has been acquired

  已经研究了钯（0）催化的烯丙基取代的机理，目的是发现中间（π-烯丙基）钯配合物是否可以以合成方式替代众所周知的抗机理而出现。使用（二苯基膦基）乙酸酯作为离去基团和立体化学偏向的底物30b和35b，已经获得了用于顺式立体化学的证据（30b → 31和35b → 36）。起始烯丙基酯中的严重空间拥塞促进了立体化学的这种逆转（这损害了普通的抗-机制），并通过Pd（0）试剂与离去基团的预配位得到增强。后者的作用显然降低了活化熵。与环己烯衍生物10b的，18B，和19B和无环衬底25b中，其中的空间位阻不操作，该抗-mechanism产生η 3 -complexes占优势甚至对于（二苯基膦基）乙酸盐。在升高的温度下，η快速平衡3 -complexes（13 ⇄ 14和20 ⇄ 21在与亲核试剂反应之前已观察到）。该作用归因于作为钯的配体的（二苯基膦基）乙酸根离子的存在。

• Nickel-Catalyzed Coupling Reaction of 1,3-Disubstituted Secondary Allylic Carbonates and Lithium Aryl- and Alkenylborates
  作者：Yuichi Kobayashi、Ryo Mizojiri、Eitatsu Ikeda

  DOI：10.1021/jo960458c

  日期：1996.1.1

  This account describes coupling reaction of 1,3-disubstituted secondary allylic carbonates with lithium aryl- and alkenylborates in the presence of a nickel. catalyst. Berates examined are 4, 5, and 6, and reactivity and selectivity were investigated using the allylic carbonates la and Ib. Coupling of la,b with berates 4 was effected with the nickel catalyst, NiCl2(PPh(3))(2) or NiCl2(dppf), in THF at 45-65 degrees C to provide products 3 in good yields with almost 100% regio- and stereoselectivities. Trivalent organoboranes prepared from acetylenes by hydroboration with catecholborane also underwent coupling reaction with la,b after transformation to berates 5 with MeLi. Though coupling using 4 and 5 required elevated temperature (45-65 degrees C), cyclic berates 6 prepared in situ from boronates 8 and MeLi were found to couple with la,b at room temperature or below. Regio- and stereoselectivities were almost 100% as were observed in the cases of 4 and 5. In these reactions, palladium complexes such as Pd(PPh(3))(4), Pd-2(dba)(3) . CHCl3 + 2 PPh(3) showed no catalytic activity. Stereochemical aspect of the present reaction was studied using cyclohexenyl carbonate 24 with 2-furylborate 4e and phenylborate 6a, and was found to proceed with overall anti fashion. With additional experiments, the mechanism of the present reaction was discussed in terms of transient pi-allylnickel intermediates.
