The preparation of fluorine-18 labeled o-fluorophenols at high specific activity is challenging and requires use of [18F]fluoride ion as the radioisotope source. As a novel, alternative approach, we found that treatment of α-diazocyclohexenones with Selectfluor and Et3N·3HF followed by HF elimination and tautomerization afforded o-fluorophenols regioselectively and rapidly. To adapt this chemistry to 18F radiolabeling, using bromine electrophiles in place of Selectfluor gave the o-fluorophenol via an α-bromo-α-fluoroketone intermediate in lower but still reasonable yields.

Two steroid estrogens, natural estradiol and 8?±-estradiol, were fluorinated using Selectfluor?? in ionic liquid. Unexpectedly, mostly products of fluorination at position C-10 were isolated instead of corresponding fluorophenols, as it was reported previ

Selectfluor was shown to be soluble in ionic liquid, thus allowing the 'green' electrophilic fluorination of activated aromatic systems compounds in high chemoselectivity and yields.
Direct Fluorination of Biologically Interesting Compounds Using N-Fluoro-3,5-Dichloropyridinium Triflate

Complete series of 2-halo- and 2-cyano-oestrogens have been prepared in good to high yields: 2-chloro, 2-bromo, 2-iodo, and 2-cyano derivatives via oestrogen-thallium (III) bis(trifluoroacetate) intermediates, and 2- and 4- fluorooestrogens by direct functionalization using N-fluoropyridinium triflate.
Method of preparing 2-fluoro-17β-estradiol

, (2008/06/13)
2-Fluoro-17β-estradiol is synthesized by mercurating a 17β-estradiol diacylate or dietherate at C-2, replacing the mercury group with fluorine and then cleaving the acyl or ether protecting groups.
