α的螯合辅助钯催化的C = C键的断裂,β不饱和酮向腈的存在形式烯腈,公开了一种正式基交换反应的配制为C的基础上,1 = C 2 + C 3 →C 1 = C 3 + C 2,从正常烯烃氧化裂解和复分解型不同。分离出的关键活性 Pd(II) 配合物以及氘标记实验揭示了螯合基团的必要性,并提出了一条合理的催化途径。
A chelation-assisted palladium-catalyzed C═Cbond cleavage of α, β-unsaturated ketone to form alkenyl nitrile in the presence of nitrile is disclosed on the basis of a formal group-exchange reaction formulated as C1═C2 + C3 → C1═C3 + C2, differing from normal alkene oxidative cleavage and metathesis type. The isolated key active Pd(II) complex as well as deuterium-labeled experiment revealed the necessity
