If links of that kind realiability would satisfy you,
task for students: http://www.tutorvista.com/content/chemistry/chemistry-iii/hydrocarbons/benzene-preparation.phphttp://www.most.gov.mm/techuni/media/ECh2011_Tex.pdf
(b) Write equations for the following:
i. Phenol reacts with NaOH
ii. Phenol reacts with bromine
iii. Phenol distilled with zinc dust
iv. Phenol heated with NH3 and ZnCl2http://img7.imageshack.us/img7/4523/benzene.jpg

If you want an original refference, i think this can help (taken form http://www.orgsyn.org/orgsyn/prep.asp?rxntypeid=116&prep=CV6P0150
Other procedures include zinc-dust distillation, not generally useful except for exhaustive degradation of phenols to hydrocarbons, and various sodium and liquid ammonia cleavages of phenol ethers.[3,4,5,6,7] These latter reactions lack generality and are often unpredictable. They require conditions too harsh for certain aromatic substituents, and the yields are frequently low.
