Trichlorofluoromethane → Agn-PC-0nfb2Y

Participants

Reaction Steps

a process wherein trichlorofluoromethane is added to 1,2-dichlorodifluoroethylene or carbon tetrachloride is added to chlorotrifluoroethylene to obtain 1,1,2-trifluoropentachloropropane, which is then oxidized and esterified to form a 2,3-dichlorotrifluoropropionic acid ester, followed by dechlorination of the ester; (2) a process wherein bromine is added to chlorotrifluoroethylene to obtain 1,2-dibromo-1-chlorotrifluoroethylene, which is then subjected to an addition reaction with propylene, followed by dehydrobromination to obtain 5-bromo-4-chloro-4,5,5-trifluoropentene-2 (CF2BrCFClCH=CHCH3), which is then oxidized and esterified to form a 3-bromo-2-chlorotrifluoropropionic acid ester, which is in turn dehalogenated; and (3) a process wherein chlorotrifluoroethylene is subjected to an addition reaction with hydrogen bromide, followed by dehalogenation to obtain trifluoroethylene, which is then subjected to an addition reaction with ICl, followed by dehydrochlorination to obtain trifluoroiodoethylene, which is then reacted with metallic magnesium in ether to form an organomagnesium intermediate, which is in turn reacted with carbon dioxide, followed by hydrolysis to obtain perfluoroacrylic acid, which is then esterified.
