A highly selective Lewis acid-catalyzed ring expansion of methylenecyclopropyl hydrazones to isomeric cyclic diazadienes is reported.Abstract:
A highly selective Lewis acid-catalyzed ring expansion of methylenecyclopropyl hydrazones to isomeric cyclic diazadienes is reported. In general, good to excellent yields and selectivities were obtained for a broad range of hydrazone derivatives.read more

Rapid Generation of Molecular Complexity in the Lewis or Brønsted Acid-Mediated Reactions of Methylenecyclopropanes
TL;DR: Lewis and Brønsted acids can be used as catalysts or reagents in the reactions of MCPs with a variety of substrates, and substituents on the terminal methylene or on the cyclopropyl ring of M CPs significantly affect the reaction pathways.

Rhodium(II)‐Catalyzed Intramolecular Cycloisomerizations of Methylenecyclopropanes with N‐Sulfonyl 1,2,3‐Triazoles
TL;DR: A novel rhodium(II)-catalyzed tandem cycloisomerization of methylenecyclopropanes (MCPs) with N-sulfonyl 1,2,3-triazoles with distinct feature of this divergent synthesis is that different types of substrates control the reaction pathways.
