Reaction with xenon difluonde

Carboxylic acids react with xenon difluonde to produce unstable xenon esters The esters decarboxylate to produce free radical intermediates, which undergo fluonnation or reaction with the solvent system Thus aliphatic acids decarboxylate to produce mainly fluoroalkanes or products from abstraction of hydrogen from the solvent Perfluoro acids decarboxylate in the presence of aromatic substrates to give perfluoroalkyl aromatics Aromatic and vinylic acids do not decarboxylate [91] (equation 51)... 

Silyl enol ethers are fluonnated in high yields with xenon difluonde [62 93, 94 95] Applications of this reaction to the preparation of fluonnated... 

Trimethylarsine gives a 98% yield of trimethylarsine difluoride when treated with xenon difluoride [102] in fluorotrichloromethane, and tris(pentafluorophen-yl)arsine gives a 94% yield of tns(pentafluorophenyl)arsine difluonde after reaction with dilute fluorine in fluorotrichloromethane at 1-0 °G [106] Other tnvalenl arsenic compounds have also been fluorinated with xenon difluoride [ 103] In addition, arsines have been oxidatively fluorinated by iodine pentafluoride [107] or electrochemically in 26-34% yield [108]... 

Xenon difluonde reaction with nitro enolates provides a useful entry into a wide variety of fluonnated synflietic intermediates [91 92] (equation 52)...
