Electrophilic Selenium Catalysis with Electrophilic N-F Reagents as the Oxidants.
A suitable oxidative system is crucial to electrophilic selenium catalysis (ESC). This short review offers the overview of recent development in ESC with electrophilic N-F reagents as the oxidants. Several highly selective transformations of alkenes such as allylic or vinylic imidation, pyridination, syn-dichlorination, oxidative cyclization and asymmetric cyclization have been described.
متن کاملThe protective effect of selenium nanoparticles and selenium against paracetamol
Objective(s): Nanotechnology has enabled researchers to synthesize nanosize particles that possess increased surface areas. Compared to conventional microparticles, it has resulted in increased interactions with biological targets.The objective of this study was to determine the protective ability of selenium nanoparticles compared to selenium against parasetamol hepatotoxicity and GPX concentr...
متن کاملNOVEL REAGENTS FOR CREATINE KINASE
The purpose of this investigation was to develop a simple colorimetric method for creatine kinase (CK). The new method is based on the reaction of creatine, formed enzymatically from creatine phosphate and ADP, with different glyoxal compounds. Hydrated glyoxals, such as para-nitrophenyl, 2-thiophene, 4- biphenyl, 4, 4' -biphenyl,α-naphthyl, β-naphthyl, para-chlorophenyl, and styryl were...
متن کاملSelenium Stabilized Carbanions. a-Lithio Selenoxides as Reagents for the Synthesis of Olefins, Allyl Alcohols, and Dienes'
Techniques for the preparation of a-lithio selenoxides have been developed. These reagents react cleanly with most aldehydes and ketones to give 0-hydroxy selenoxides, which can be thermolyzed to allyl alcohols or reduced to &hydroxy selenides, The P-hydroxy selenides are further transformed to olefins by reductive elimination. a-Lithio selenoxides can also be alkylated and acylated, although t...
متن کاملComplement Proteins and Reagents
The complement system is a complex cascade involving proteolytic cleavage of serum glycoproteins often activated by cell receptors. This cascade ultimately results in induction of the inflammatory response, phagocyte chemotaxis and opsonization, and cell lysis. Complement factors C3a, C5a, and C4 can induce vasodilatation, increased capillary permeability, and expression of leukocyte adhesion m...
