Trifluoroacetyl hypochlorite

Sodium salts of fluoroacids react with chlorine fluoride at —112 to —78°C to give explosively unstable fluoroacyl hypochlorites. Trifluoroacetyl hypochlorite and its pentafluoropropionyl, heptafluorobutyryl, difluoroacetyl and chlorodifluo-roacetyl analogues explode without fail if the partial pressure exceeds 27-67 mbar. Hexafluoroglutaiyl dihypochlorite explodes above — 10°C [1]. Of the 4 compounds prepared, acetyl, propionyl, isobutyryl and pivaloyl hypobromites, the 2 latter appeared stable indefinitely at —41°C in the dark, while the 2 former exploded unpredictably as isolated solids [2],...

Olefin inversion (c/. 7, 338). Trifluoroacetyl chloride reacts with 1,2-dialkyl epoxides in DMF stereospeciflcally by trans opening to give u/c-chlorohydrin trifluoroacetates. These products are reduced stcrcospccifically by Nal to alkenes with. ryn-elimination to give inverted alkenes. Reductions with zinc arc less selective. Inversion of olefins is also possible by addition of NCS in CFjCOOH (actual reagent is trifluoroacetyl hypochlorite) followed by reduction with Nal. [Pg.419]
