Abstract The synthesis of [14 C]-labelled glycidyl ethers and the corresponding glycerol ethers is described for the monofunctional compounds 1-dodecanol and ortho-cresol and the bifunctional compounds 4, 4′-dihydroxy-3, 3′, 5, 5′-tetramethyl biphenyl and 1, 6- hexanediol. The synthesis is based on reaction between the alcohol and [U-14 C]-epi- chlorohydrin (1). The aromatic compounds have been converted to the corresponding ...
