Abstract:
Intramolecular rearrangements of methoxysiloxycarbene (CH3OCOSiH3) have been investigated by means of ab initio molecular orbital theory and hybrid density functional theory calculations. Particular attention was paid to 1,2-silyl migration from oxygen to the carbene carbon, and to the analogous 1,2-methyl migration for comparison. A combination of frontier molecular orbital (FMO) theory, natural bond orbital (NBO) analysis, and the theory of atoms in molecules (AIM) were used to shed light on the mechanistic details of these rearrangements. The present analyses clearly indicate that 1,2-silyl

Galanthamine is one of only a few drugs that is licenced for the treatment of Alzheimer's disease. It is manufactured through an inefficient synthetic process or extracted from members of the Amaryllidaceae plant family. In this work a range of structurally related alkaloids was semisynthesised from galanthamine and used as standards to assist with the search for alkaloids that may make a good starting point in the semisynthesis of galanthamine. The search was targeted on the effluent from the production line of Alzeim Ltd., a company that extracted galanthamine from members of the Narcissus g

Abstract:
This chapter deals with electrophilic rearrangements in which a group migrates formally as cationic species. It mentions the intramolecular electrophilic rearrangement which has four electrons involved in the transition state, of which one pair is accommodated in an antibonding orbital of the migrating species. It also describes the anionic migration terminus that acts as the nucleophile. The chapter considers the interaction of the highest occupied molecular orbital (HOMO) with the lowest unoccupied molecular orbital (LUMO) of the migrating group.

Abstract:
This chapter reviews arbitrary distinction to create the classification of aromatic rearrangements. It considers reactions that are initiated by the generation of an arenium ion and involve migration around the aromatic ring or from a side chain onto the aromatic nucleus. It also points out that the migration terminus positioned on an aromantic ring is initiated by protonation or by a Lewis acid, which is commonly a consequence of equilibration to form thermodynamically stable products. The chapter highlights intramolecular migration, which occurs via a π-complex that leads to equilibration be

Abstract:
This chapter focuses on insertion reactions, wherein the overall effect of the reaction bears no relationship to the mechanism and is accomplished by a variety of small molecules. These reactions are most commonly achieved by sulfur dioxide, alkynes, alkenes, carbon monoxide, and nitric oxide, which can be inserted into metal-carbon bonds and metal-hydrogen bonds. The mechanistic description of the reaction is typically that of an intramolecular migration process. The chapter outlines the general principles of the mechanism in relationship to alkenes, carbon monoxide, and nitric oxide.

Abstract:
Direct methanol fuel cells (DMFCs) are considered as a competitive power source candidate for portable electronic devices. Nafion® has been widely used for the electrolyte of DMFCs because of its good proton conductivity and high chemical and mechanical stability. However, the major problem that must be solved before commercialization is the high methanol crossover through the membrane. There are a number of studies on experiments about the methanol crossover rate through the membrane but only few theoretical investigations have been presented [1–3].
