1 Introduction
As a noble metal, silver becomes one of the most important metals in the life of
human beings, which has been used as currency and ornaments by humans for
thousands of years. Nowadays, silver and its salts have been widely used in
photography, electrical equipment, jewelry, as well as transition metal for catalysis
in chemistry. In chemical research, silver complexes were usually thought to be low
activity and used as either co-catalysts [1, 2] or Lewis acids [3] for decades. In
recent years, a wide range of important organic transformation has been catalyzed
by silver complexes, including C–H insertion, amination/amidation, fluorination,
hydrosilylation, decarboxylation, and so on [4–12].
Direct sp
3 C–H bond functionalization has attracted much attention in the past
few decades, which presents high efficient, atom-economical pathways to construct
new functional groups from easily available chemicals. Most of present C–H bond
transformations need to use expensive metals, such as palladium, rhodium, iridium,
etc. [13]. Compared to these metals, silver is relatively economically attractive and
has been proved highly efficient for C–H activation in recent years, in particular,
silver-mediated sp
3 C–H bond transformation. Diverse Ag complexes exhibited
