 some light on the constitution of the compound whence it is derived. 



Action of Chloracetic Ether upon Triethylphosphine. 



The reactions which I have described were also applied to triethyl- 

 phosphine. Repetition of all the phenomena previously observed 

 with triethylamine. Triethylphosphine and chloracetic ether com- 

 bine with evolution of heat and formation of a brownish liquid of 

 considerable consistency. If somewhat larger quantities are to be 

 mixed, it is desirable to moderate the action by the presence of a 

 volume of anhydrous ether, equal or greater than the aggregate bulk 

 of the two liquids. Dissolved in water, separated by filtration or di- 

 stillation from the excess of chloracetic ether employed, and mixed 

 with dichloride of platinum, the new chloride furnishes a beautifully 

 crystallized platinum-salt, which, after several crystallizations from 

 boiling water, exhibits the composition 



C 10 H 22 P0 2 Pt C1 2 = [(C 2 H 5 ) 3 * p ] Cl, Pt Cl. 



Submitted to the action of oxide of silver, the chloride contained in 

 this platinum- salt undergoes the same change which was observed 

 in the corresponding nitrogen compound, 



Hj H 



It is scarcely necessary to point out the perfect analogy of the new 

 phosphoretted compounds with the corresponding bodies in the nitro- 

 gen-series. Whatever view be entertained of the latter, must also be 

 taken regarding the former. Conceived in the anhydrous condition, 

 the product obtained by the action of oxide of silver upon the chloride 

 may be considered as phosphoretted glycocoll with three equivalents 

 of ethyl in the place of three of hydrogen, 



C 8 H 17 P0 2 =C 2 H 2 (C 2 H 5 ) 3 P0 2 . 



The phosphoretted compound resembles in its properties the sub- 

 stance derived from triethylamine. The aqueous solution, when 

 evaporated in vacua, solidifies into a radiated crystalline mass. I
