Donor and donor–donor carbenes are two important kinds of carbenes, which have
experienced tremendous growth in the past two decades. This review provides a …

Radical cascade reactions are an attractive tool for the rapid construction of complex
molecular architectures. Although a large number of powerful radical cascades have been …

Donor/donor carbenes are relatively new in the field of carbene chemistry; although
applications in C− H and X− H insertion reactions are few in number, they demonstrate …

Discovered as organometallic curiosities in the 1970s, carbene radicals have become a
staple in modern-day homogeneous catalysis. Carbene radicals exhibit nucleophilic radical …

N-Tosylhydrazones have recently emerged as useful synthons in a variety of transition-metal-
