Abstract

This review article summarizes progress in N-alkylations, N-alkenylations, N-and C-arylations and hetarylations, halogenations, as well as organometallic chemistry of pyrazoles mainly achieved during the last decade. In addition, the generation and chemistry of N-heterocyclic carbenes of pyrazole (pyrazol-3-ylidenes) and remote N-heterocyclic carbenes of pyrazole (pyrazol-4-ylidenes) are described.
