ethanol. S 1992, 965<br />
Fluorination<br />
* Bromofluorination of alkenes In combination with Hydrogen Fluoride-Pyridine complex or Silicon (IV)<br />
Fluoride. TL 1991, 32, 69<br />

Coupling. TL 1991, 32, 69<br />
* Dithiolanes to gem difluoro compounds JOC 1986, 51, 3508<br />
Halogenation<br />
* Arene to haloarene Bromination of aromatic rings, even electron deficient ones, occurs in the<br />
presence of strong acids. BCJ 1994, 67, 1918<br />
* Arene to haloarene Electrophilic bromination of electron rich aromatics. TL 1997, 38, 4415<br />
