$Boger Pyridine Synthesis Mechanism | Organic Chemistry The mechanism for a Boger pyridine synthesis via hetero-Diels−Alder reaction of 1,2,4-triazines and dienophiles followed by extrusion of N2 to yield the final product. Music: Alone – Infraction$ $Adding Nosyl Group Mechanism | Organic Chemistry The mechanism for the addition of a Nosyl protecting group which is commonly used as a protective group for amines, and therefore allows for easy conversion to the free amino compound. Music: Dreamy – Infraction$ $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. Music: Abstract Wall – Infraction$ $Paternò–Büchi Reaction Mechanism | Organic Chemistry The mechanism for a Paternò-Büchi reaction which is the photo-catalyzed electrocyclization of a carbonyl with an alkene to form polysubstituted oxetane ring system. 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.

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