The results of the present study indicate the superiority of ATC over other NIs, including DCD, encapsulated calcium carbide and pyrazoles
, as reported in some earlier studies conducted at 35[degrees]C with NIs and N[H.
Synthesis and structure-activity relationship studies of urea-containing pyrazoles
as dual inhibitors of cydooxygenase-2 and soluble epoxide hydrolase.
flavones, isoxazolines, isoxazoles, pyrazolines and pyrazoles
Inhibition of the oxidation of the urinary bladder carcinogen N-butyl-N-(4-hydroxybutyl) nitrosamine by pyrazole
and 4-substituted pyrazoles
Other subjects covered include synthesis and electronic properties of assemblies of diastereomers of nickel II complexes with tetracyanometalates, synthesis of functionalized pyrazoles
, stereochemical aspects of interaction between some monosaccharides and l-alpha-amino acids in aqueous solutions, and challenges in carbohydrate chemistry.
However, Beauchemin, along with graduate student Joseph Moran and undergraduate student Tanya Suen, have shown that efficient 1,4-additions of imidazoles, pyrazoles
, and triazoles can be accomplished under optimized conditions (Equation 1).
Organophosphates, carbamates, pyrethroids, and phenyl pyrazoles
insecticides are typically used to manage this pest.
The intermediate compounds may undergo a single cyclization to the desired pyrazoles
, or once the pyrazoles
are formed this compound can undergo a second cyclization to a new fused-ring system, pyrazoloimidazolediones.
This is the case, in particular, of insecticides for the protection of various crops, particularly in view of the combination of Bayer and ACS's portfolio of products in two very successful new classes of chemical substances, neonicotinoids, where Bayer controls the main products, and pyrazoles
, which are unique to ACS.
and isozazoles  have been the subject of chemical and biological studies due to their interesting pharmacology including antipyretic, analgesic, antiinflammatory potential herbicidal, fungicidal and leishmanicidal [7-10] properties.
He has assembled information for coordination chemists from over 1,300 papers covering 1999 to 2007 in a style that largely follows the original but expands to include recent studies on scorpionate ligands that feature heterocycles other than pyrazoles
