Trans-Cinnamic Acid - an overview | ScienceDirect Topics

Weigh 1.5 g of trans-cinnamic acid, and place in a 100 ml Erlenmeyer. Add approximately 2 ml of THF. Heat (water bath, see p. 83), mixing until the cinnamic acid is dissolved. When it has dissolved, remove the Erlenmeyer flask from the heat and gently stir by hand to form on the flask wall a film with the solid as homogeneous as possible.

Stereochemistry: Addition of Bromine to Trans-Cinnamic .

Use perspective drawings, Fischer Projections and words, to demonstrate whether syn addition of bromine to trans-cinnamic acid results in Isomer I or Isomer II. Repeat the process for anti addition. NOTE CAREFULLY:The question is about mode of addition (syn vs. anti), not mechanisms; do not use curved arrows to explain your answer.
