PERKIN, Jr., W. H., 1885. 



Ber. 18, 218-220; J. Chem. Soc. 48, 515. 



Dehydracetic Acid. 



The subject of the constitution of dehydracetic acid is reviewed and 

 the formula CO 2 HC< ^ H )Q >CCH 3 , is advanced. The methyl 



ester melts at 90.5, is soluble in water and the solution is decidedly 

 acid. From the methyl ester and sodethoxid the compound Cg H 6 Na 

 CH 3 O 4 is formed.

New Method of Introducing Nitrogenous Radicals in Malonic and 



Acetoacetic Esters. 



This is by the action of imido-chlorids, benzanilidimido-chlorid, C& 

 H 5 C1=N CsHj, for instance. The chlorin is eliminated and the 

 remaining monad radical is substituted. The author is working in this 

 line.

Some derivatives of Triphenyl=carbinyl-bromid. 



When sodacetoacetic ester is treated with triphenyl-carbinyl-bromid, 

 C Br (C6H 5 ) 3 , there is produced triphenyl-carbinyl-acetoacetic ester, 

 CH 3 CO C[C(C 6 H 5 ) 3 ] 2 CO 2 C 2 H 5 , a substance which melts at 159.5 to
