[2][3] This modification of the Wurtz reaction is considered a separate process and is named for both scientists.
[1] The reaction works best for forming asymmetrical products if the halide reactants are somehow separate in their relative chemical reactivities.
With the use of ultrasound sodium reacts with some aryl halides to produce biphenyl compounds.
[14] One example is the conversion of tetraethyl orthosilicate to the mono-tert-butoxy derivative in 40% yield as summarized in this idealized equation:[15] Molten sodium was used.
Other organosilicon compounds synthesized using the Wurtz–Fittig reaction include silylated calixarenes[16] and vinylsilanes.
