Catalytic Effect of Ferrous Chloride in Chloroarylation of Styrene
Styrene reacts with arenediazonium chlorides in the presence of FeCl2 as catalyst to give 1-chloro-1-phenyl-2-arylethanes along with minor amounts of 1,4-diaryl-2,3-diphenylbutanes. Ferrous chloride turned out to be a more active catalyst in the chloroarylation of styrene than copper chlorides.

Reaction of m-Phenylenebisdiazonium Salts with Unsaturated Compounds
Main route of the reaction between m-phenylenebisdiazonium tetrafluoroborate with unsaturated compounds (acrylonitrile, styrene, alkyl acrylates and methacrylates) in the presence of NaCl and a catalyst (CuCl2) is the Meerwein chloroarylation by one diazogroup; the second diazogroup is replaced by chlorine according to Sandmayer's reaction.
