| The most important chemical classes of these so-called auxin herbicides include chlorophenoxy acids, benzoic acids, pyridines, and quinoline carboxylic acids. |
| It has been shown that electron transfer fluorescence quenching does take place in quinoline betaines compounds. |
| Cinchonidine, when heated with potassium hydrate, yields quinoline also, and with nitric acid the same products as cinchonine. |
| Enone 1 reacts under Michael conditions with malononitrile to give the quinoline derivative. |
| Most of these are of a basic character, and belong to the pyridine and the quinoline series. |
| When cinchonine is distilled with solid potassium hydrate, it yields pyrrol and bases of both the pyridine and quinoline series. |
