Technical Notes: 1. High yield synthesis of diarylacetylenes via the copper(I) catalyzed coupling of aryl iodides and phenylacetylene. 2. High yield synthesis of 1,3-enynes via the copper(I) catalyzed coupling of vinyl iodides and phenylacetylene. 3. Catalyst used in the high-yielding cycloaddition of terminal alkynes and azides to form triazoles. 4.
L1 and L2 ligands were prepared by the condensation of 1,10-phenanthroline-5,6-dione with 5-bromosalicylaldehyde and 2-hydroxy-4-methoxybenzaldehyde, respectively. The structures of the compounds were determined by elemental analyses, IR,UV-visible, 1H-NMR, TGA, magnetic susceptibilities and molar conductance measurements.
Buy 3-Bromo-1,10-phenanthroline (CAS 66127-01-3), a biochemical for proteomics research, from Santa Cruz. Molecular Formula: C12H7BrN2, MW: 259.11.
The invention relates to a preparation method for N-phenyl-3-bromocarbazole. The preparation method comprises a first step of preparing 3-bromocarbazole by employing carbazole as a raw material and DMF as a solvent, adding dibromohydantoin for bromination, controlling a temperature to be not higher than 20 DEG C, reacting for 5-6 hours, filtering and recrystallizing; and a second step of.

A novel synthesis of indoles having electron withdrawing substituents in the 3-position has been developed. Various 2-nitrostyrenes were prepared via Stille coupling of 2-tributyl stannyl-2-propenoic acid ethyl ester with substituted 2-bromo-l-nitrobenzenes. Alternatively, sequential vicarious nucleophilic substitution of substituted nitrobenzenes and Knoevenagel condensation with formaldehyde.
Syntheses and Characterization. 5-bromo-1,10-phenanthroline (5-Br-phen). In a thick wall bomb flask equipped with a PTFE stopper and a magnetic stirring bar, 3.60 g (20.00 mmol) of anhydrous 1,10-phenanthroline (phen) were dissolved in 14 mL of fumic.
