Treatment of one stereoisomer of (2 ?, 3R)-2-iodo-3-phenylbutane with base, yields (E)-2-phenylbutene.
a) Determine which enantiomer of 2-iodo-3-phenylbutene gives the E product (2R, 3R or 2S, 3R), and explain clearly (using unambiguous diagrams) why that is the case.
b) Assign that enantiomer as either R or S at carbon 2.
each successive hydrogen is more easily substituted until the trihalo species is obtained. Explain
