  practical synthesis of these compounds. In sharp contrast, hydrovinylation of a variety of 1,3‐dienes is best catalyzed by nickel(II) complexes of 2‐benzyloxyphenyldiphenylphosphine, L5. The other two ligands, 2‐benzyloxymethyl‐ (L6) and 2‐benzyloxyethyldiphenylphosphine (L7) are much less effective in the HV of 1,3‐dienes.

  用2-苄氧基，2-苄氧基甲基或2-苄氧基乙基-苯基部分取代三苯膦中的一个苯基会产生一组简单的配体，这些配体在各种镍（II）催化的烯烃二聚反应中表现出截然不同的行为反应。配体与2-苄氧基苯基和2-苄氧基甲基苯基二苯基膦的配合物（分别为L5和L6）对乙烯基芳烃的氢乙烯基化（HV）最具活性，前者导致伯3-芳基-1-丁烯广泛异构化为共轭物2-芳基-2-丁烯即使在-55°C下也可以。但是，2-苄氧基甲基取代的配体L6该化合物的活性略低，在环境温度下可提供定量的HV初级产品定量收率，而没有异构化的痕迹，因此为这些化合物的实际合成提供了最佳选择。与之形成鲜明对比的是，2-苄氧基苯基二苯基膦L5的镍（II）配合物最好地催化了各种1,3-二烯的氢乙烯基化。其他两个配体，2-苄氧基甲基-（L6）和2-苄氧基乙基二苯基膦（L7）在1,3-二烯的HV方面效力低得多。镍（II）催化的1,6-二烯环化异构化为亚甲基环

  Cyclic and acyclic 1,3-dienes undergo efficient (substrate/catalyst = 72) heterodimerization with ethylene in the presence of a Ni catalyst prepared from [o-(PhCH2O)]C6H4PPh2, [(allyl)2NiBr]2, and Na+ BAr4- (Ar = 3,5-bis-trifluromethylphenyl), giving 1,2-addition products. Yields up to 99% can be realized for several 1-vinylcycloalkenes and 1-substituted 1,3-butadienes. Phospholanes with suitably placed hemilabile ligating groups and phosphoramidites derived from binaphthol are excellent ligands for an asymmetric variation of this reaction, the latter giving 99% yield and >95% ee's for selected substrates. An example of how an exocyclic chiral center can be used to install other stereo-centers in the ring (e. g., the carbon to which the side chain is attached) is also provided. These discoveries open an expeditious entry into several biologically relevant classes of compounds, especially those carrying tetrahydronaphthalene and related heterocyclic moieties.

  The addition of ethylene to 1,3-dienes and 1-vinylcycloalkenes, catalyzed by two ruthenium complexes, proceeds in a regioselective fashion to afford 3-methyl-1,4-dienes as products. For a steroidal-based 1-vinylcycloalkene, the addition is stereospecific, giving a product with a 20(S) configuration.
