The latter may attack the quinone at a — C H = g r o u p ; they may attack at a carbon atom carrying a halogen or other group, ultimately with expulsion of this g r o u p ; or they may add across the conjugated system (or across both ene-one systems of benzoquinone). A n early example of analytical application of reaction(s) with quinones is the test of Ehrlich and Herter< > published in 1904.
