Bridging vinyliminium diiron complexes 1, easily accessible by insertion of alkynes (HCCR’) into the metal-carbon bond of diiron mu-aminocarbynes1, exhibit a remarkable reactivity, that allows the preparation of a variety of highly functionalised mu-hydrocarbyl ligands. The reactions include: a) addition of NaBH4, selectively directed to Calpha or Cbeta; b) deprotonation of Cbeta-H, generating an unstable intermediate, which can be functionalised upon treatment with unsaturated molecules: isocyanides, CS2 diazo-compounds.

Abstract
Bridging vinyliminium diiron complexes 1, easily accessible by insertion of alkynes (HCCR’) into the metal-carbon bond of diiron mu-aminocarbynes1, exhibit a remarkable reactivity, that allows the preparation of a variety of highly functionalised mu-hydrocarbyl ligands. The reactions include: a) addition of NaBH4, selectively directed to Calpha or Cbeta; b) deprotonation of Cbeta-H, generating an unstable intermediate, which can be functionalised upon treatment with unsaturated molecules: isocyanides, CS2 diazo-compounds.File in questo prodotto:
