Perfluoro tertiary alcohols I. Synthesis of high molecular weight perfluorinated monoketones and tertiary alcohols

摘要: Abstract A series of high molecular weight perfluoro ketones, R f 1 C(O)R 2 ( II ) and alcohols,R −R 3 COH( III [R , : n-C 6 F 13 (CF CFO(CF CF x =1 2), C 5 O(C 4 O) y =4 5), O[CF CF(CF )O] 7 O[CF(CF )CF O] ; :(CF CFOCF where may be thesame or different, has been prepared in good to excellent yields. This was accomplishedby the reaction appropriate perfluoroorganometallic reagent diethyl carbonateor perfluoroalkylether ester under suitable conditions yield symmetric asymmetricketones ). These ketones were then reacted with lithium,containing an oxygen atom β carbon attached lithium, produce tertiaryalcohols The alcohol is influenced by type perfluoroorganometallicreagents, mode addition solvents.
