The method is applicable for triorganoarsenic compounds bearing aryl or vinyl substituents (equations 76 , 77 and 78 ), while for the preparation of alkylarsenic halides this method has not been useful since only adduct formation and redox reactions have been reported between R3AS and AsXj (equations 79a and b) . Reaction of tris(trifluoromethyl) arsine with arsenic iodide, however, has been reported to afford a mixture of halides (equation 80) . In the reaction of unsymmetrically substituted compounds such as 4, cleavage of the aryl-arsenic bond is preferred to that of the alkyl-arsenic bond (equation 78 ). The cleavage of 4 by this method is in contrast to that of 3 in thermolysis (equation 75). 

The period of systematic development of arsenic drugs commenced at the end of the nineteenth century, and brought about some remarkable improvements in medicine. Arsenic compounds, administered as Fowler s solution (potassium arsenite), Donovan s solution (arsenic iodide) or de Valagin s solution (arsenic trichloride), were employed to treat rheumatism, arthritis, asthma, malaria, trypanosome infections, tuberculosis, and diabetes. N-Acetylar-sanilic acid (C8H10ASNO4), and primarily Sal-varsan (arsphenamine, C12H14AS2CI2N2O2) were discovered by Ehrlich in 1909, and remained in use to treat syphilis until the advent of antibiotics in the 1940s (Baumler...

August Arthur Plisson ( -Paris, June 1832 from cholera) was assistant and finally head apothecary in the Hospital k la Pitie (Paris). He published on asparagine and discovered aspartic acid, and arsenic iodides. Henry and Plisson described a method of combustion analysis. ...
