From the experiments described in literalure and from their own eaperiments the authors conolude thai at 1070 temperaturs (e. g. 7 8 O C.) the addition of Itrl lo a douhle bond o[ the structure is an easy process, but is more difficult for the double bond - C = C - and demands H II Hie ol a tise catalysl such as Al C13, which causes a pait /el polymerisation.

Several experimenk on this subject have been tertiary chlorides. The tentiary chlorides must bc handled described already in the litenakurel. It might be useful very care, ully. The higher the moiecular weighl of these to summarize the experience obtained in this field of chlorides the easier hydrochloric acid is split olf again reseaxch, also by the results of series of experiments at temperatiir es higher than the reaction temperature2. that were made hy the lauthors and that have not yet The addition proceeds rapidly and the yield of the been published. The authors will not give details, only corresponding tertiary chloride is high as by the low the general principles and facts that oan be deduced temperature and the absence of a catadyst the principal from the results of the experiments will be mentioned reaction is not disturbed by side rcactions. here. However, the mono olefines with the structure -C=C- at -78°C. practically do not react with hydro-The experiments were carried out at about -78°C. H I3 (-70" to -78°C.). At this temperature a great number oî chloric acid under the same condilions.
