| Zusammenfassung: | 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 in multigram 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-bromoketone) derivative 4B. |
