A critical objective for the continued advancement of the field of asymmetric catalysis is the design and implementation of novel activation modes that allow the invention of unprecedented transformations. Recently, our laboratory introduced a new mode of organocatalytic activation, termed (singly occupied molecular orbital) SOMO catalysis, that is founded upon the transient production of a 3π-...

background: the goal of this study was to survey the total residual chlorine and chloroform in the water distribution system of isfahan, iran, and zoning of obtained results using gis. methods: in this cross-sectional study, total residual chlorine was tested in the sampling points of the water distribution system of isfahan and chloroform was measured with standard methods and after transferri...

The palladium catalysed cross-coupling of organosilicon reagents with organo halides and pseudo-halides has developed over the past 30 years into an efficient and attractive carbon-carbon bond forming strategy. Extensive research within this field to expand and diversify on the scope of the organosilicon coupling reaction will continue to promote its use in the synthesis of biologically and pha...

A large variety of environmental carcinogens are metabolically activated to electrophilic metabolites that can bind to nucleic acids and protein, forming covalent adducts. The formation of DNA-carcinogen adducts is thought to be a necessary step in the action of most carcinogens. Recently, a variety of new fluorescence, immunochemical, and radioactive-postlabeling procedures have been developed...
