Organic Acid Phosphides. 

 P. N. Evans. 



" Phosphorus in the organic phosphines shows such a perfect analogy to 

 nitrogen in the amines, that it seems strange that we should not be familinr 

 also with tlie phosphorus analogues of the acid amides— which we may 

 appropriately call phosphides. Of this class of bodies no mention is made 

 in most books on organic chemistry, and an examination of the literature 

 shows only two of these substances to have been prepared and very super- 

 ficially investigated, namely, mono- and tri-chlor-acetyl phosphides, dating 

 back to the seventies. 



With a view to preparing other representatives of this class and ex- 

 amining them, the methods used to make the acid amides were considered 

 as to their applicability; the reaction between hydrogen pb^sphlle (PH3) 

 and acid chlorides seemed to be the most promising by which to attempt 

 to prepare new acid phosphides.
