4‐Biphenylylcalcium Iodide and 9‐Phenanthrylcalcium Bromide: Grignard‐Type Reagents of Polycyclic Aromatic Hydrocarbons. Issue 32 (20th June 2013) - Köhler, Mathias
Abstract Reduced to the max: Halogenated polycyclic hydrocarbons can be reduced with calcium via two different pathways yielding radical anions due to electron transfer into the π*‐orbital or Grignard‐type reagents due to insertion of Ca into the carbonhalogen bond (see figure).
