Dieser Reaktionsverlauf ist insofern überraschend, als die Abspaltung von Halogenwasserstoff (im Beispiel Bromwasserstoff) nicht, wie man hätte erwarten sollen, nach dem tertiär gebundenen Wasserstoff atom, sondern ausschließlich nach der endständigen Methylgruppe hin erfolgt, ein Vorgang, der wohl ohne Beispiel dastehen dürfte und sich infolgedessen in keiner Weise voraussehen ließ. Daß die Neigung des Halogens, mit einem Wasserzutreten, hier auffallenderweise eine sehr große ist, folgt auch daraus, daß ζ. B. auch aus den halogenisierten Basen von der FormelThis course of the reaction is surprising insofar as the elimination of hydrogen halide (in the example hydrogen bromide) not, as one should have expected, after the tertiary hydrogen atom, but takes place exclusively after the terminal methyl group, a process that probably could stand there without example and, as a result, could not be foreseen in any way. That the tendency of halogen to step into water with a water, strikingly a very great one here is, it also follows that ζ. B. also from the halogenated bases of the formula
