Most highly branched perfluoro ethers, particularly those sterically crowded around the oxygen, are currently inaccessible synthetically by conventional Synthetic techniques used in organofluorine chemistry. Such compounds are of unusual biomedical interest currently because they have been found'to be good oxygen carriers and quite surprisingly not to be retained in the liver. Previously linear ethers were thought by biomedical researchers to ...
