Christina White's Very Awesome Webpage

For the 10th and final blog of the semester and ever for organic chemistry, Dr. Mullins explained that we would need to check out Christina White's webpage and explain how the reaction deals with the schemes we have studied in class.  One publication that I found very interesting and quickly noticed similarities in the reaction was for the publication 19.  The reaction deals with reaction schemes listed in chapter 26 of the organic chemistry book.  The reaction scheme is shown as:

In Christina White's publication is titled as "Synthesis of Complex Allyclic Esters via C-H Oxidation vs C-C Bond Formation."  This publication deals with the C-H bond oxidation method for the synthesis of allyclic esters.  This reaction scheme is a olefin metathesis which reacts with a grubbs catalyst to produce the final products.  The olefin metathesis occurs in the presence of a complex transition metal catalyst that contains a carbon-metal bond. 2 The first step in the olefin metathesis, two molecules of the starting alkene are arranged adjacent to each other. 2  Then, the double bonds are broken which forms two new double bonds using carbon atoms that were not previously bonded to each other in the starting alkenes. 2 The final two products show that the overall reaction and experiment was completed correctly.
