Phenyl iodosotrifluoroacetate

Acyclic ADC compounds, which are more correctly named as derivatives of diazene, are generally prepared from hydrazine derivatives. For example, diethyl azodicarboxylate (Chemical Abstracts name diethyl diazene-1,2-dicarboxylate)5 is prepared from hydrazine by treatment with ethyl chloro-formate followed by oxidation with chlorine in benzene-water.6 Other oxidants which have been used include JV-bromosuccinimide,7 nitric acid,8 inorganic nitrates,9 potassium dichromate,10 silver carbonate on celite,11 and phenyl iodosotrifluoroacetate.12 The hydrazine derivative may also be... 

Phenyl iodosotrifluoroacetate added to a soln. of phenacyl iodide in dry dichloro-methane, stirred at room temp, for 17 h, and the crude product subjected to silica gel column chomatography eluting with methanol and dichloromethane phenacyl alcohol. Y 74%. F.e.s. J.H. Boyer, A. Natesh, Synthesis 1988, 980-1.
