摘要:Novel fluorinated carboxylic acid derivatives of the general formula: ##STR1## wherein Rf is a divalent perfluoroalkyl or perfluoropolyether group and Z is halogen, hydroxyl or triorganosiloxy are useful intermediate for the synthesis of various fluorinated compounds. Compounds [I-i] wherein Z in formula [I] is F are prepared by reacting acid fluoride-terminated compounds of the formula: ##STR2## with an alkali fluoride and further with an allyl halide. Compounds [I-ii] wherein Z in formula [I] is a halogen are preparred by reacting compounds [I-i] with lithium halide. Compounds [I-iii] wherein Z in formula [I] is OH are prepared through hydrolysis of compounds [I-ii]. Compounds [I-iv] wherein Z in formula [I] is triorganosiloxy are prepared by reacting compounds [I-iii] with a triorganosilylating agent.
