Mononuclear Heterocyclic Rearrangements

Tetrahedron, 1974
Publisher Summary This chapter discusses the mononuclear heterocyclic rearrangements. The chapter discusses the ring conversion of type 1→2 characterized by nucleophilic attack from a Z atom on a sp 2 -nitrogen atom with displacement of an atom. On this basis, the known ring conversions are tabulated. Taking into account the reactivities observed
