80 BIBLIOGRAPHY OF 



is formed, a pale yellow liquid boiling at 245° to 247.° By repeating 

 former experiments with acetoacetic ester and formamid, a liquid boil- 

 ing at 250° to 255° was obtained which was mono-lutidin-carboxylic 

 ester and which apparently is isomeric with Michael's body of the same 

 name which he obtained from aldehyde, aldehyde ammonia and 

 acetoacetic ester.

Action of Acetoacetic Ester on Hydrazo-benzene. 



When acetoacetic ester is treated with hydrazo-benzene, Ce H5 

 NH — NHCe H5 , a compound C16 Hj^ N2 O. which melts at 120° and 

 is weakly basic and acid is formed. It is probably a phenylated

 Phenyl Mercaptan and Acetoacetic Ester. 



By treating a mixture of two molecules phenyl mercaptan and one 

 molecule acetoacetic ester with hydrochloric acid, /9 dithiophenylbutyric 

 ester, CH3C (SC6H5)2CH2 CO2 C^ Hs, is obtained; it melts at 57°-58°,
