Synthesis of crude product.
1. Combine reagents (following either step A or B, depending on the
benzaldehyde assigned to
you). It is best not to use a brand-new conical vial right out
of the package, as the surface is not rough enough to help induce
precipitation.
A. In a 5-mL conical vial, combine 0.15 g of 3-nitrobenzaldehyde
(151.121 g/mol), 0.12 mL
of acetophenone (120.151 g/mol; d = 1.03 g/mL), and 0.80 mL of

Why is it important to completely dissolve both the alkene and alkyne before adding the pyridiumium tribromide to the reaction vial. Why is this important? Hint: the alkene and alkyne do not have the same solubility in acetic acid. this is the experiment, In the fume hood, measure 2.0 mL of glacial acetic acid into your 10 mL microscale reaction vial. Add trans-stilbene (135 mg, 0.75 mmol) and diphenylacetlyene (135 mg, 0.75 mmol). Add a stir bar and place the...
