Leaving Group Conversions - SOCl2 and PBr3
6 problems
Problem 1Multiple Choice
The following reaction is another method to synthesize haloalkanes using reagents other than PBr3 and SOCl2. Propose an arrow-pushing mechanism that rationalizes the production of chloroalkane in the given reaction. (Hint: Begin by reacting dimethyl sulfide and Cl2. DMS is an excellent nucleophile, whereas Cl2 is an electrophile.)
Problem 2Multiple Choice
What is the alcohol needed to produce the given bromoalkane using PBr 3 as a reagent?
Problem 3Multiple Choice
Give the reagent that will produce the stereochemical outcome for the reaction shown below.
Problem 4Multiple Choice
Give balanced chemical equations for the reactions shown below.
Problem 5Multiple Choice
Provide the products that will form when the molecule below is allowed to react with the following reagent: (i) SOCl2, NEt3.
Problem 6Multiple Choice
Provide compounds (i)-(vi).
