Lee, Ka Young,Lee, Chang Gon,Kim, Jae Nyoung
, p. 1231 - 1234 (2007/10/03)
Synthesis of N-tosylimines of arylaldehydes was carried out by the reaction of arylaldehydes and p-toluenesulfonamide in methylene chloride in the presence of trifluoroacetic anhydride as a dehydrating agent.

We have developed a convenient synthetic approach to highly reactive N-(arylsulfonyl)trichloro- and -trifluoroacetimidoyl chlorides 2 by reacting the corresponding N-acylsulfonamides with PCl5. The interaction of the imidoyl chlorides with phos
TRANSFER OF THE DIAZO FUNCTION IN THE SERIES OF FLUORINATED 1,3-DIKETONES
Nikolaev, V. A.,Utkin, P. Yu.,Korobitsyna, I. K.
, p. 1059 - 1061 (2007/10/02)
In the reaction of fluorinated 1,3-diketones with p-toluenesulfonyl azide under the conditions of diazo transfer hydrolytic elimination of the perfluoroacyl group occurs, and acyldiazomethanes are formed instead of the fluorine-containing diazo diketones.The reaction can be used for the synthesis of difficultly obtainable and labile 2-diazo ketones.
