Tunicates are marine animals that are called "sea squirts" because when they are taken out of water, they tend to contract and expel seawater. Lepadiformine is a cytotoxic agent (toxic to cells) isolated from a marine tunicate. During a recent synthesis of lepadiformine, the investigators observed the formation of an interesting by-product (3) while treating diol 1 with a reagent similar in function to PBr3 (J. Org. Chem. 2012, 77, 3390–3400):

For problem 8.17, all of the reactions will be SN2. For each reaction, identify and evaluate each nucleophile (strong? weak? Strong or weak as a base?) Also, evaluate each solvent as polar protic or polar aprotic. I recommend drawing the structure of each solvent.

Compound X is insoluble in cold KMnO4, Br2 in CCl4, and conc. H2SO4. Compound X is most likely: a. an alkane b. none of these c. an alkene d. an alcohol e. an alkyl halide Indicate which of the ff. statements regarding nucleophilicity is incorrect. F- is more nucleophilic, hence, more reactive towards methyl iodide than Cl-. Second row elements are more nucleophilic than first row elements of comparable basicity. The rate of SN2 reaction may be markedly affected by the nucleophilicity of the attacking atom. Nucleophilicity is the affinity of a nucleophile to an electrophilic carbon Which of the following alkynes can be deprotonated by NaNH2 in liquid NH3? 3-Methylhex-2-yne Pent-2-yne 3-Methylbutyne none of these Hex-3-yne
