Procedure
3-[(Hydroxy)methyl]phenol was dissolved in acetonitrile (300 ml) and dichloromethane (900 ml) and the resulting mixture was poured in the flask kept under argon; magnetic stirring was set on. The solution was then cooled with an ice bath and carbon tetrabromide and triphenilphosphine were added. The latter was added in small portions in order to maintain the temperature at ca. 2-3° C.
