Abstract
Tetraphenylmethane (1) and several functionalized tetraphenylmethanes 4-7, all of them useful building blocks for the construction of tetraarylmethane frameworks, are readily synthesized by improved standard procedures inmultigram quantities. The structure of compound 5 has been additionally corroborated by an X-ray structure analysis. The novel class of tetrakis(thiazolylphenyl)methanes 8 showing a significant blue emission upon UV-excitation can be prepared in good yield by Hantzsch synthesis starting from the tetra(α-bromoketon) derivative 4b.
