119-91-5, 2,2′-Biquinoline is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

A Zn(NO3)2*6H2O dissolution (10.3 mg, 0.0346 mmol/2 ml ethanol:water 1:1) was added to another dissolution of thiosaccharine (12.3 mg, 0.062 mmol/2 ml ethanol:water 1:1). Finally, solid 2,2′-biquinoline was added (9.4 mg, 0.0367 mmol/2 ml ethanol:water1:1). A pale yellow powder was then obtained. Yield: 90%. Molar conductivity (mS M1) = 26.3. Analytical percent composition calculated for C32H20N4O4S4Zn: C = 53.520%; H = 2.807%; N = 7.801%. Found: C = 53.884%; H = 2.761%; N = 7.698%. Soluble in DMSO and DMF.

119-91-5, 2,2′-Biquinoline is a catalyst-ligand compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Cu(NO3)2.4H2O (103 mg, 0.4 mmol) and Na(dca) (71 mg,0.8 mmol) were dissolved in ethanol (60 ml) and stirred withheating to 343 K. To this hot solution, a solution of biq (205 mg, 0.8 mmol) in acetonitrile (75 ml) was added and stirring was continued for about 40 min. The resulting redsolution was filtered into a beaker and left undisturbed in thedark at room temperature. After 10 d, dark-green tabular crystals were obtained. The crystals were collected by filtration,washed with acetonitrile and dried in air [yield: 93 mg,26%, based on Cu(NO3)2.4H2O]. Elemental analysis (%)calculated for C44H24Cu2N16: C 58.47, H 2.68, N 24.79; found:C 58.36, H 2.71, N 24.86. IR (KBr, cm-1): 3631 (w), 3126 (w),3058 (w), 2347 (s), 2268 (s), 2210 (s), 2160 (s), 1618 (w), 1594(m), 1550 (w), 1509 (w), 1432 (w), 1381 (s), 1340 (m), 1290 (w),1214 (w), 1159 (w), 1102 (w), 971 (w), 914 (w), 819 (s), 781 (m),755 (m), 742 (m), 619 (w), 531 (w).

As the paragraph descriping shows that 119-91-5 is playing an increasingly important role.
