Hazard Predictions

• Generates heat: Exothermic reaction at ambient temperatures (releases heat)

The combination of aryl halides with organometallic compounds can result in an exothermic reaction under some conditions. Caution should be used before proceeding. Further research of comparable examples in the literature or very small scale, carefully controlled experiments may be needed to fully assess compatibility.

The C-X bonds of aryl halides can be broken by some organotransition metal compounds in a process called oxidative addition. A new metal-carbon bond and a new metal-halide bond are formed. The product is itself an organometallic compound and may be reactive and possibly pyrophoric (Rothenberg, G. 2010. Catalysis. Kirk-Othmer Encyclopedia of Chemical Technology. (Online)).
