  Thermal decomposition of structurally related amido, alkoxo, and alkyl complexes of type [Ni(Me)(EC(H)RR′)(dippe)] (EC(H)RR′ = cyclo-NC4H8 (pyrrolidino), N(CH2Ph)2, OCH2Ph, OCH(Me)Ph, and CH2CH2Ph) takes place through formally analogous processes involving β-hydrogen elimination and reductive elimination of methane, cleanly affording corresponding Ni(0) imine, aldehyde, ketone, and olefin complexes

  [Ni（Me）（EC（H）RR'）（dippe）]类型的结构相关的酰胺基，烷氧基和烷基络合物的热分解（EC（H）RR'=环-NC 4 H 8（吡咯烷基），N （CH 2 Ph）2，OCH 2 Ph，OCH（Me）Ph和CH 2 CH 2 Ph）是通过形式类似的过程进行的，包括β-氢消除和甲烷的还原消除，干净地得到相应的Ni（0）亚胺，醛，酮，和烯烃络合物，[镍（η 2 -E═CRR'）（dippe）]。对这些分解反应的动力学研究表明，尽管它们具有相似性，但它们仍存在很大的机理差异。
• Nickel-Catalyzed Reductive Hydroesterification of Styrenes Using CO₂ and MeOH

  Complexes [(dippe)Ni(mu-H)](2) (A) (dippe = 1,2-bis-di-isopropylphosphino)ethane) and [(dtbpe)Ni(mu-H)](2) (B) (dtbpe = 1,2-bis-di-tert-butylphospino)ethane) catalyze the reductive hydroesterification of styrenes with the use of CO2 and MeOH. The latter acts as a hydrogen source and as an esterificating agent, to yield the corresponding branched and linear esters in moderate to good yields. In all of the studied reactions the linear esters were obtained in higher amounts than the branched ones. When the hydroesterification reaction was carried out using a stoichiometric metal/substrate ratio, the complexes [(P-P)Ni(CO)(2)] and [(P-P)Ni(CO3)] (P-P = dippe or dtbpe) were isolated and characterized by standard spectroscopic methods. Compounds [(dtbpe)Ni(CO)(2)] and [(dtbpe)Ni(CO3)] were also fully characterized by single-crystal X-ray diffraction.
