It was also observed that increasing the bulk of the R group on the diketone and using methoxy-substituted anilines leads to the formation of 2-CF3-quinolines.
Polyaniline was first described in the mid-19th century by Henry Letheby, who investigated the electrochemical and chemical oxidation products of aniline in acidic media.
In 1862, Henry Letheby obtained a partly conductive material by anodic oxidation of aniline in sulfuric acid.
In 1826 at the age of 20, Unverdorben discovered aniline, which he obtained from the distillation of natural vegetable indigo.
They decided to enter a partnership to manufacture aniline in Germany, setting up a factory at the Rummelsburg Lake near Berlin.

Paul Mendelssohn Bartholdy (born Paul Felix Abraham Mendelssohn Bartholdy; 18 January 1841, Leipzig – 17 February 1880, Berlin) was a German chemist and a pioneer in the manufacture of aniline dye.
The first aniline dye-stuff to be prepared on a manufacturing scale was mauveine, which was obtained by Sir William Henry Perkin by heating crude aniline with potassium bichromate and sulfuric acid.
None of the in vivo or in vitro studies performed with toxic-oil-specific components, such as fatty acid anilides and esters of PAP, have provided evidence that these markers are causally involved in the pathogenesis of TOS.
