which both prove the erythro-2‚3-dibromo-3-phenylpropanoic. Determination of the Stereochemistry of 2‚3-dibromo-3-phenylpropanoic acid. Introduction The purpose of this experiment was to determine the mechanism of the reaction of trans-cinnamic acid with the addition of bromines to 2‚3-dibromo-3-phenylpropanoic acid. An addition of bromine was added to trans-cinnamic acid and it is necessary to determine whether the intermediates were syn or anti addition or a mixture of them both to find the stereochemistry

nitrogens on this station. Both of these methods rely on the repulsive electrostatic interactions between the positively charged axial component and the post-switching cationic nature of the benzidine station (Figure 5.4). Deuterated trifluoroacetic acid (d-TFA) was added in the solution which resulted in the protonation of the benzidine residue and shuttling of macrocycle in to the biphenol station of the Rotaxane. This was supported by NOESY 1H NMR that showed a shift in the peaks in retrospect to

LAB REPORT! EXPERIMENT#5‚6! MANPREET KAUR KHAIRA! LAB PARTNER: VIAN RAIES! The purpose of this lab exercise was to perform the bromination of (E)-1‚2-diphenylethene (trans-stilbene) by addition reaction in which bromine was added across the double bond to yield a vicinal dibromide. The next step was to perform a double elimination reaction by product gained to synthesize an alkyne‚ that is‚ 1‚2-diphenylacetylene. The two major techniques used in this lab were TLC analysis and UV-vis spectroscopy
