Purpose

• In these experiments triphenylmethanol is
  dissolved in highly acidic medium forming the
  propeller-shaped triphenylmethyl carbocation. The
  resulted carbocation reacts quickly with methanol
  or bromide ion to give the target compounds.

Comments

• Follow pp. 478-481 (microscale).
• Follow the lab handout for all experimental
  procedures. Wearing rubber gloves is necessary
  during this lab. You will work with corrosive and
  harmful compounds.
• Determine mp and calculate yield of final
  products. Low to moderate yields should are
  typical.

Safety

• Concentrated sulfuric acid and hydrobromic acid
  are corrosive, handle with care.
• Triphenylmethyl derivatives are corrosive and
  irritating to eyes, respiratory system and skin.
  Do not swallow and inhale, avoid contact with
  skin and eyes. Wear eye protection and rubber
  gloves.
