heptafluoroisopropoxylation reactions through the invention of a series of redox-active N-OCF(CF3)2 reagents. These reagents were readily prepared from the oxidative heptafluoroisopropylation of hydroxylamines with AgCF(CF3)2. The substitutions on the nitrogen atom significantly affected the properties and reactivities of N-OCF(CF3)2 reagents. Accordingly, two types of N-OCF(CF3)2 reagents including N-OCF(CF3)2
