## Abstract The utility of [^18^F]fluoromethyl tosylate as an [^18^F]fluoromethylation reagent has been reexamined. The preparation of this potentially useful compound from the reaction of __bis__(tosyloxy) methane with ^18^Fβ was reported several years ago, but it had not found use as a labeling r
mixture with heptane, from which it is crystallized a t -80 "C. The yield was 27 % calculated on the total amount of starting material, and 54 "/, on the amount consumed. CzH5Cp2ZrCI is a crystalline, intensely yellow, diamagnetic compound [xg = -(0.44 & 0.04) x 10-6 E.M.U./g], which is decomposed
