The invention also relates to said iodo- or astatoarene and diaryliodonium compound as such. The invention also concerns a method of synthesizing a iodo- or astatolabelled biomolecule and/or vector using said iodo- or astatoarene.Aryliodonium salts have become increasingly popular in the last decades for arylation of nucleophiles thanks to their low toxicity, the high regioselectivity they allow and the mild reaction conditions they require compared to conventional methods. Halogens were amongst the first nucleophiles to be closely investigated for the nucleophilic aromatic substitution of aryliodonium salts more than 50 years ago. Yet, this is only recently that applications related to halogenation with these precursors have been developed, especially in radiochemistry with the radiolabelling of arenes with the β-emitter fluorine-18 for positron emitted tomography (PET).In contrast to F, the other radiohalogens have received limited attention for reaction with iodonium salts. For instance, no report exists as to the reactivity of radioactive bromide, iodide and astatide.Many of the radioiodinated and astatinated compounds of interest in nuclear medicine are aromatic derivatives since non-aromatic compounds often exhibit poor stability due to the weakness of the C—I and C—At bonds. These aromatic compounds are generally obtained by conventional methods such as nucleophilic ...

Disclosed herein are methods for synthesizing 1,2,5,6-hexanetetrol (HTO), 1,6 hexanediol (HDO) and other reduced polyols from C5 and C6 sugar alcohols or R glycosides. The methods include contacting the sugar alcohol or R-glycoside with a copper catalyst, most desirably a Raney copper catalyst with hydrogen for a time, temperature and pressure sufficient to form reduced polyols having 2 to 3 fewer hydoxy groups than the starting material. When the starting compound is a C6 sugar alcohol such as sorbitol or R-glycoside of a C6 sugar such as methyl glucoside, the predominant product is HTO. The same catalyst can be used to further reduce the HTO to HDO.
