摘要:

AbstractDescriptions are given of different methods of preparation and proofs of the structure of six bromopyridines (2,3‐dibromo‐, 2,4‐dibromo‐, 3,4‐dibromo‐, 2,3,4‐tribromo‐, 2,4,5‐tribromo‐, and 2,3,4,5‐tetrabromopyridine), while at the same time some of their chemical properties, in particular their reaction with ammonia, are discussed.In conclusion a survey is given of some of the physical properties of the bromopyridines which are now all known; the boiling points of these substances

摘要:

Abstract2‐Phenylazocrotonic acid ethyl and methyl ester were investigated as examples of compounds containing a conjugated system consisting of an NN double bond conjugated with a C‐C double bond. It was found that ozone combines by addition to the CC double bond, hydrogen and hydrochloric acid in the 1:4 position, the last substance splitting off alcohol at the same time and forming 1‐phenyl‐3‐methyl‐4‐chloropyrazolone‐5, while the action of phenyl magnesium bromide was exactly comparable with the action of the same subs
