"Chemistry scheme shows that the substrate with one R group does not react under the rhodium-catalyzed reflux conditions. Three equivalents of the S-configured substrate with two R groups form a cis dirhodium complex. C11, with bromine, forms in 56 percent yield. C12, with trimethylsilyl or triethylsilyl groups, gives no product. C13, with para-phenylphenyl groups, forms in 30 percent yield, and C14, with para-trifluoromethylphenyl groups, forms in 21 percent yield."
