Action of Acetoacetic Ester on Cinnamaldehyde. 



When acetoacetic ester, cinnamaldehyde and ethylen-diamin are 

 mixed and heated, a reaction takes place and a crystalline substance, 

 C21 H26 Oe is formed which melts at i6o°-i6i.° It will give a bromin 

 derivative and is decomposed by caustic potash. Methylamin or anilin 

 may be used in place of ethylendiamin without changing the result. 

 If benzaldehyde be used in place of cinnamaldehyde a compound free 

 from nitrogen is obtained but if propaldehyde is used a compound con- 

 taining nitrogen is produced.

Action of Acetoacetic Ester on Dextrose in 

 Alcoholic Ammonia. 



In this reaction two compounds are formed, Cj6 H26 Os N a neutral 

 substance which melts at i89°-i90° and C10H16O5N, which melts at 

 i30°-i3i.° The latter was formed in sealed tubes at 100° to lio.° The 

 author is continuing the investigation of these reactions.

In the researches upon these compounds the first one was made from 

 acetoacetic ester. Sodacetoacetic ester was treated with trimethylene 

 bromid and after the reaction more sodium dissolved in alcohol was
