KINETICS OF THE METHYL-IODIDE CATALYZED AND AUTOCATALYZED ARBUZOV REARRANGEMENT (METHOXYPHOSPHONIUM, CONDUCTIVITY, PHOSPHORUS NMR)
Rates for the two sequential steps of the Arbuzov rearrangement: (UNFORMATTED TABLE FOLLOWS) MeI ABPOMe (--->) ABP(O)Me, A, B, = OMe, OMe;(TABLE ENDS) OMe, Ph; Ph, Ph; OMe, Et; and Et, Et were measured by conductivity. The concentration of the methoxyphosphonium iodide intermediates was determined …

Novel approaches to the synthesis of selenium modified nucleosides, nucleotides and nucleic acids
… pore glass (CPG) which underwent Michaelis – Arbuzov (M-A) reactions with nucleoside-3ʹ-H-phosphonates. All sixteen possible 5ʹ-phosphoroselenolate-linked canonical dimer motifs were synthesised. The support bound thymidine analogue was also used in the synthesis of a tetranucleotide sequence …

Design and synthesis of functional graphenic and triptycene poli(arylether) materials
… Chapter 2: Using a modified version of the Arbuzov reaction, graphene oxide is covalently functionalized with phosphonate functionalities. Due to the oxidizing nature of graphene oxide, the reaction produces a large amount of phosphate salts which organize around the covalently installed …

Synthesis of phosphorus/sulfur-based antivirals
The Human Immunodeficiency Virus is a major global health problem. Although a number of effective combination therapies are available, drug resistance remains an ongoing concern due to the rapid mutation rate of the virus. Novel antivirals are continually required to combat evolving resistance. By …
