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 C IO H IO N 2 O , before described, is now supposed to 

 have the formula 



CH NH

and is named oxymethylquinizin. The reaction between phenylhy- 

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

 (i) C 6 H 5 NHNH 2 + CH 3 COCH 2 CO 2 R = CH 3 CCH 2 CO 2 R 



A 

 HN-N-C 6 H 5 



and (2) this loses alcohol and leaves CH 3 CCH 2 CO 



A 



HN-N-C 6 H 4 . 



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

 among them were orthotoluoxymethylquinizin, paratoluoxymethyl- 

 quinizin and /3-napthodiinethyloxyquinizin.
