Abstract
The hydroamination of alkynes using o-aminophenol proceeds in very high to good yields in the presence of Pd(NO3)2 catalyst. Remarkable rate enhancement with o-aminophenol is presumably due to the chelation effect of the ortho OH group to palladium.
摘要
在硝酸钯催化剂存在下，使用邻氨基酚对炔烃进行氢胺化反应，产率非常高或良好。邻氨基酚显著提高反应速率可能是由于邻位羟基对钯的螯合作用。
