Radical and Nitrenoid Reactivity of 3-Halo-3-phenyldiazirines

3-Halo-3-phenyl-3H-diazirines (halogen = Br or Cl) undergo a dissociative single-electron transfer from alkyllithiums (RLi) in THF-based solvent mixtures. The resulting 3-phenyldiazirinyl radical, observed by EPR spectroscopy, is eventually transformed to benzonitrile. In Et2O, 2 equiv of RLi add to both nitrogens of halodiazirine N=N bond, affording N,N′-dialkylbenzamidines. The nitrenoid reactivity of some N-alkyl-1H-diazirine intermediates is manifested by their insertion into the α-C-H bond of THF or Et2O.

Samarium diiodide promoted synthesis of N,N′-disubstituted amidines

An efficient one-step preparation of an N,N′-disubstituted amidine by the direct nucleophilic addition of an amine to the parent nitrile using catalytic amounts of SmI2 under relatively mild conditions is developed. Alkyl, benzyl and aryl amidi
