Palladium(II) acetate is a versatile, inexpensive, and simple catalyst for the selective N-monoalkylation of amino derivatives with poor nucleophilic character, such as aromatic and heteroaromatic amines as well as carboxamides, sulfonamides, and phosphazenes, using, in all cases, primary alcohols as the initial source of the electrophile, through a hydrogen autotransfer process.

乙酸钯(II)是一种通用,廉价且简单的催化剂,用于在所有情况下均使用以下方法,对具有不良亲核特性的氨基衍生物(例如芳族和杂芳族胺以及羧酰胺,磺酰胺和磷腈)进行选择性N-单烷基化。通过氢自动转移过程,伯醇作为亲电子试剂的初始来源。苯并噻唑-2-胺烷基化的区域选择性与使用卤化亲电试剂发现的区域选择性相反。 醇-烷基化-胺-氢转移-钯
