  摘要：

  已经研究了丁烯内酯在电还原环化反应中作为底物的潜在用途。已经研究了在附接的侧链上带有α，β，不饱和酯，α，β，δ，不饱和酯，烯丙基溴，溴化物，甲磺酸酯或醛官能度的各种丁烯化物。这些系统在电还原环化反应条件下的性能受到丁烯内酯环的C5和附加侧链的C1处酸性质子的存在的严重限制。

  A method for hydroformylating or hydrocarbonylating a substrate having a carbon-carbon double or triple bond or both is described. The method comprises exposing the substrate to a hydroformylation catalyst under an atmosphere comprising carbon monoxide and hydrogen in the presence of a regeneration reagent so as to form a product. The regeneration reagent is such that it is capable of at least partially reversing poisoning of the hydroformylation catalyst by a diene or an alkyne or both.
