Derivatives of Acetophenonacetoacetic Ester and Acetonylaceto= 



acetic Ester. 



One of the two isomeric compounds Cu HjoO, obtained by dehydrat- 

 ing acetophenon-acetone is named dehydraceto-phenon-acetone 

 and given one of the three formulae : Ce H5C : C CH2 CO CH3 ; 

 Ce H5 COCH3 C ; CCH3 ; C6 H5 COCH2 CH2 C : CH ; and the other 



CH : C ( CH3) 

 compound is named phenyl-methyl-furfurane , I > O .

Derivatives of Carbamid. 



The author is investigating the products of the action of carbamid 

 on acetoacetic ester. From the first compound formed C5 Hg N2 O3, are 

 obtained C5 He N^ O^ ; C5 H3 N3 Oe ; C4 H3 N3 O^ and C5 He N4 O3.
