H2O,H2SO4 1. (sia) BH 2. NaOH, H202
Predict the major organic product. 1) Sia BH 2) NaOH, H202
Draw the expected product. Hint: Assume BH3 works like
(sia)2BH.
Does that mean we Hydroboration-Protonolysis on the triple bond
in this structure, turning it into a cis-alkene?

1. (sia)2BH 2. H2O2, NaOH 3. H2Cr04 4. SOCI2 5. H2C=CHCH2OH CECH Work out the above synthesis on a separate sheet of paper, and then draw the organic product of reaction 3. • You do not have to consider stereochemistry. • You do not have to explicitly draw H atoms. • Do not include lone pairs in your answer. They will not be considered in the grading. • Do not draw organic or inorganic by-products.
