    The Formation and Properties of Some 2 : 5- and 2 : 6-Substituted Pyrazines and their Conversion into Amino-ketones and Imino-diketones. By Frank Tutin. In a recent communication (Tutin, Caton, and Hann, Trans., 1909, 95, 2113) it was shown that the action of ammonia on w-chloro- jj-hydroxyacetophenone did not result in the formation of w-amino- y)-hydroxyacetophenone, but yielded only resinous products. This result was considered somewhat remarkable, inasmuch as the analogous chloro-mp-dihydroxy-ketone readily yields the correspond- ing amine (D.R.-P. 155632). The behaviour of a number of
