[RhCp*Cl2]2 can catalyze the oxidative coupling of secondary isonicotinamides with activated olefins using Cu(OAc)2 as an oxidant. The selectivity can be controlled by the solvent. In MeCN, the mono-olefination and two-fold oxidation reaction is the major pathway, while in THF this reaction gave mostly diolefination products. In both cases, the coupled products contain an exocyclic CC bond.
[RhCp*Cl2]2能催化次异烟酰胺与活泼烯烃的氧化偶联反应,以Cu(OAc)2作为氧化剂。通过溶剂可以选择性地控制反应。在
乙腈中,单烯化与双氧化反应是主要途径,而在
四氢呋喃中该反应主要得到二烯化产物。两种情况下,偶联产物都含有一个环外碳碳键。
