Magnetic Rotary Polarization of Compounds in Relation to 

 Chemical Structure. 



Tables of very many substances are given, among them are : — 

 Acetoacetic ester at 16.25° specific rotation =0.9278 and molecular 

 rotation = 6.501. Allylacetoacetic ester at 13.9° specific rotation 

 = 1.09022 ; molecular rotation = 10.382.

Action of Acetoacetic Ester on Phenylhydrazin. 

 Quinizin Derivatives.* 



The compound CioHio N2 O , before described, is now supposed to 



have the formula 



CH — NH 

 / \ N I 

 HC C/ \CCH3,

\ / N /

H O 



and is named oxymethylquinizin. The reaction between phen3'lhy- 



drazin and acetoacetic esters is general and consists of two parts : — 



( I ) Ce H5 NHNH2 + CH3 COCH2 CO2 R = CH3 CCH2 CO2 R 



A 

 HN-N-C6H5 



and (2) this loses alcohol and leaves CH3 CCH^ CO 



^ A I 

 HN-N-C6H4. 



This substance was studied and a number of its derivatives described, 



among them were orthotoluoxymethylquinizin, paratoluoxymethyl- 



quinizin and /9-napthodimethyloxyquinizin.
