Concept introduction:
The nucleophilic substitution reactions are the reactions in which one nucleophile is substituted by another nucleophile. These reactions depend upon the nucleophilicity and concentration of the nucleophile. There are two types of nuclephilic substitution reaction.

- Wittig reactions with the following -chloroethers can be used for the synthesis of aldehydes and ketones. (a) Draw the structure of the triphenylphosphonium salt and Wittig reagent formed from each chloroether. (b) Draw the structural formula of the product formed by treating each Wittig reagent with cyclopentanone. Note that the functional group is an enol ether or, alternatively, a vinyl ether. (c) Draw the structural formula of the product formed on acid-catalyzed hydrolysis of each enol ether from part (b).arrow_forwardDraw structural formulas for (1) the alkyltriphenylphosphonium salt formed by treatment of each haloalkane with triphenylphosphine, (2) the phosphonium ylide formed by treatment of each phosphonium salt with butyllithium, and (3) the alkene formed by treatment of each phosphonium ylide with acetone.arrow_forwardDesign and draw a catalytic cycle for the production of butanal from prop-1-ene. Recognize which step responsible for the selectivity of formation of the n- or iso-isomer.arrow_forward
- Provide the structure of the major organic product in the substitution reaction of 3-iodocyclopentene with water.arrow_forwardArrange the relative stability of the intermediates involved in the addition addition of hydrogen halide to alkene.arrow_forwardProvide a name for the molecule below and indicate whether it is the "diene" or "dienophile" Name: furan-2,5-dione It is a: dienophilearrow_forward
- How are cyclopropanes synthesized from alkenes using carbene reactants and how is the mechanism understood to predict the products. Also, what are the various methods for generating carbenes (including the preparation of Simmons-Smith reagents)arrow_forwarda) Cycohexanone reacts with 1,3-propanediol under acid catalysis to form the cyclic acetal. Write down the reaction mechanism and explain why the use of cyclic acetals as protecting groups is preferred over open- chain acetals. b) Eugenol (see below) is made from cloves. Give the structural formulas of the products which are formed after reaction of eugenol with i) BH3, then H2O2 / NaOH or after reaction with ii) acetic anhydride. OH Eugenolarrow_forwardGive structures for the product(s) formed from the other alkenes when subjected to the conditions of ozonolysis.arrow_forward
