Formation of a chiral 1-fluoro-2,2-diphenylcyclopropyl radical in the Barton decarboxylation reaction
摘要:
The chiral 1-fluoro-2,2-diphenylcyclopropyl radical (8), generated in the Barton decarboxylation reaction, was used as a probe to evaluate a variety of halogen and hydrogen atom donating reagents as radical traps.

Carbenoids, generated by metalation or halogen-metal exchange reactions, have been prepared from chiral vinyl and cyclopropyl halides. The reactivity and stereochemistry observed in the reaction of these carbenoids has been interpreted as being due to metal-assisted ionization (MAI).
