determine the major organic product for the reaction scheme shown.

by

Question 1

determine the major organic product for the reaction scheme shown.


Question 2

determine the major organic product for the reaction scheme shown.


Question 3

1) Determine the major organic product for the following reaction scheme. (If no reaction, draw the starting material.)

2) Determine the major organic product for the following reaction scheme. (If no reaction, draw the starting material.)

Gilman Reagents: Gilman reagents are organocuprate compounds used in organic synthesis. Gilman reagents can be prepared from organolithium compounds by reaction with cuprous salts like copper(I) iodide. Gilman reagents react as carbon nucleophiles.


Answer to question 1

Step 1

Step 2


Answer to question 2


Answer to question 3

1) The structure of the product is provided below:

The following steps illustrate how product was formed.

2) The structure of the product is provided below:

The following steps illustrate how product was formed.

For both reactions:

Step 1: Formation of an organolithium reagent

Step 2: Formation of a Gilman reagent (organocuprate)

Step 3: Substitution reaction with the alkyl bromide to form a new carbon-carbon bond.
