Yamada, Takayuki published the artcileFormal Lossen Rearrangement/[3+2] Annulation Cascade Catalyzed by a Modified Cyclopentadienyl RhIII Complex, SDS of cas: 1293990-73-4, the publication is Chemistry – A European Journal (2018), 24(22), 5723-5727, database is CAplus and MEDLINE.
It has been established that a cyclopentadienyl RhIII complex with two Ph groups and a pendant amide moiety catalyzes the formal Lossen rearrangement/[3+2] annulation cascade of N-pivaloyl benzamides and acrylamides with alkynes leading to substituted indoles and pyrroles. Mechanistic studies revealed that this cascade reaction proceeds via not the Lossen rearrangement to form anilides or enamides but C-H bond cleavage, alkyne insertion, and the formal Lossen rearrangement.
