The Wurtz Fittig reaction is the name given to the process for the preparation of alkylated aromatic compounds by sodium‐mediated coupling of an alkyl and an aryl halide. It was first noted in 1860.
It has been used in the preparation of 'organosilicon' compounds (for example: silicone sealants).
More than 150 years after its discovery, there are presently two competing explanations for how the reaction works - and there appears to be experimental evidence for both.
Ideas for new topics, and suggested additions / corrections for old ones, are always welcome.
