 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, 

 C 2 i H 2 6 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, C^H^OsN a neutral 

 substance which melts at 189- 190 and C IO H l6 O 5 N, which melts at 

 I 3- I 3 I The latter was formed in sealed tubes at 100 to no. The 

 author is continuing the investigation of these reactions.

 a-w-diacetyl-pentane and a-w-dibenzoyl-pentane. 



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
