Results and Conclusion/Discussion
\After step 2, the percent yield was calculated to be 237%. This was not realistic. so after concentrating it again more thoroughly using a rotary evaporator again, the percent yield was calculated, and it went down to 75%. There might have still been some solvent from the NMR in the compound. This overall was a pretty resonable value. The NMR showed that the compound for step 2 was there however, there was not a high concentration of it. Also, the product was not pure. There were a lot of imperfections. This means that of the 75% yield that was achieved, not all of it was the product that was wanted.
The NMR showed that the compound for step 2 was there however, there was not a high concentration of it. Also, the product was not pure. There were a lot of imperfections. In figure 16, the first trial, there were too many imperfections so it was uncertain whether the right compound was even made. For figure 17, the 2nd trail, where we knew the compound was is pointed out. It was compared with Ghosh’s NMR’s.
After step 2 when the brine was added to the separatory funnel to rinse the product, there was a white milk looking organic layer, so it was gravity filtered. It was found that there was a precipitate. An infrared spectra was then taken of the solid. As seen in Figure 18 there was an OH bond between 3000 to 4000 but no benzene rings between 2000-3000.
