TL;DR: The same substrate subjected to heterylation with 3,5-dinitro-1,2,4-triazole derivatives reacted selectively at the N1 atom, and its bromination afforded 3-azido-5-bromo-1-2, 4-Triazole.
Abstract: Alkylation of 3-azido-1,2,4-triazole with oxiranes, bromoacetone, and methyl vinyl ketone furnished a mixture of N-substituted 3- and 5-azido-1,2,4-triazoles, 3-azido compounds prevailing. The same substrate subjected to heterylation with 3,5-dinitro-1,2,4-triazole derivatives reacted selectively at the N1 atom, and its bromination afforded 3-azido-5-bromo-1,2,4-triazole..

TL;DR: In this paper, the reaction of bromomethylenebis(phosphonates) with electron-deficient alkenes 2a-d as Michael acceptors in the presence of thallium(I) ethoxide leads to a new and facile route to 2-substituted 1,1-cyclopropanediylbis (phosphorus) 3 in satisfactory yield.
Abstract: Reaction of bromomethylenebis(phosphonates) 1 with electron-deficient alkenes 2a-d as Michael acceptors in the presence of thallium(I) ethoxide leads to a new and facile route to 2-substituted 1,1-cyclopropanediylbis(phosphonates) 3 in satisfactory yield. These are converted into the corresponding free acids 7 by treatment with chlorotrimethylsilane in the presence of potassium iodide followed by treatment with water. The products resulted from bromomethylenebis(phosphonates) 1 and other alkenes 2 e, f and methyl vinyl ketone are identified and discussed

TL;DR: The catalytic oxidation of S(IV) species by transition metal ions (TMIs) is a significant pathway for aqueous sulfate formation as mentioned in this paper, and Sulfoxy radicals, such as SO3, SO4, and SO5− radicals, are major i...

TL;DR: In this paper, fair yields and enantiomeric excesses up to 91% were obtained in the Michael addition of cyclohexanone-2-carboxylate to methyl vinyl ketone, using (R,R)-trans-1,2-diaminocyclohexane as chiral auxiliary (37% mol/mol with respect to the donor).
