Music: Dreamy – Infraction$ $MOM Protecting Group Addition | Organic Chemistry The mechanism for the addition of a Methoxymethyl (MOM) ether group which is generally used to protect the hydroxyl group. However, it is also used to protect amino groups. MOM groups have the potential to be cleaved by refluxing in methanol or under acidic conditions.

There are multiple reagents that have the formula M[HB(sec-Bu)3] which are all used as reducing agents. There are three different cations with these reducing agents and they are L-Selectride (lithium), N-Selectride (sodium), and K-Selectride (potassium). Due to the sec butyl groups on these reducing agents, these reagents are sensitive to steric influences which has the potential to allow for stereoselective reactions.

The mechanism of the Paternò-Büchi reaction is not well known. A general pathway has been proposed and widely accepted. Büchi originally proposed that the reaction occurred by light catalyzed stimulation of the carbonyl moiety into an excited singlet state.

$Selenium Dioxide (SeO2) Oxidation Mechanism | Organic Chemistry The mechanism for an oxidation reaction using selenium dioxide (SeO2) which is an oxidizing agent generally used in the allylic oxidation of alkenes to yield allylic alcohols. These alcohols then can be further oxidized to aldehydes or ketones. Selenium dioxide is used in a similar oxidation process known as a Riley oxidation. Music: Dreamy – Infraction$

$Beirut Reaction Mechanism | Organic Chemistry The mechanism for a Beirut reaction which involves the condensation of benzofurazan oxide (BFO) with an enamine or enolate anion in an alcohol solvent to yield the corresponding quinoxaline-1,4-dioxide. The first step of the mechanism involves the nucleophilic addition of an enamine to the electrophile BFO to form the first intermediate. Ring closure then occurs via the condensation of the imino-oxide onto the iminium functionality. Finally, elimination of the dialkyl amine yields the final product.

Alcohols react with 3,4-dihydropyran to give 2-tetrahydropyranyl ethers. These ethers are stable in a variety of reactions conditions, however, the alcohol can be restored by acid-catalyzed hydrolysis. Music: Kerala – Infraction$
