Zincphenylimide. 

 , C12H5 



Zn. 



This body is produced by the action of zincethyle upon anhydrous 

 anihne. The reaction is so violent that it requires to be moderated 

 by diluting the zincethyle ^Yith ether. Heat is evolved, and a large 

 quantity of a combustible gas is rapidly generated. At length the 

 liquid becomes a white, semisolid, opake mass. Analysis proved the 

 gas to be pure hydride of ethyle, whilst the solid body regenerated 

 anihne in contact with water. The production of zincphenylimide 

 may therefore be thus expressed : — 



Zincphenylimide is a white amorphous body very similar to zinc- 

 amide. Like the latter body, it is instantly decomposed by water, 

 aniline being regenerated : —

 Diethylzincamine. 



[Zn, 

 This body is produced by the action of zincethyle upon diethyl- 

 amine. The reaction requires to be aided by heat. Pure hydride of 

 ethyle is evolved, and the following equation expresses the reaction : — 



Its reactions arc quite similar to those of the bodies a buve 

 described. 



Zincoximide.

Dry oxamidc and pure zincethyle are without any action upon each 

 other at ordinary temperatures, but the heat of a water-bath is suffi- 

 cient to establish a violent reaction, torrents of pure hydride of ethyle 

 are evolved, and zincoximide combined with zincethyle remains in 

 the retort. The following ecpiation expresses the reaction : —
