Example 2

Reactions requiring anhydrous conditions were conducted under a positive atmosphere of nitrogen or argon in oven-dried glassware. Standard syringe techniques were used for anhydrous addition of liquids. Unless otherwise noted, all starting materials, solvents, and reagents were acquired from commercial suppliers and used without further purification. Flash chromatography was performed using 230-400 mesh silica gel. Compounds 1{1}, 1{2}, 1{3}, 1{4}, 1{5}, 1{6}, 2{24}, 2{25}, 2{26}, and PAC-1 were synthesized as previously reported.

Compound Analysis. NMR experiments were recorded either in CDCl₃(Sigma), CD₃OD (Sigma) or (CD₃)₂CO (Sigma) on a Varian Unity 400 MHz or 500 MHz spectrometer with residual undeuterated solvent as the internal reference for ¹H-NMR and ¹³C-NMR experiments and 1% CFCl₃/CDCl₃as the external reference for ¹⁹F-NMR experiments. Chemical shift, δ (ppm); coupling constants, J (Hz); multiplicity (s=singlet, d=doublet, t=triplet, q=quartet, m=multiplet, br=broad); and integration are reported. High-resolution mass spectral data was recorded on a Micromass Q-Tof Ultima hybrid quadrupole/time-of-flight ESI mass spectrometer at the University of Illinois Mass Spectrometry Laboratory.

Synthesis and Characterization of Complex 1

Check if the same lab product or an alternative is used in the 5 most similar protocols

All manipulations were performed under a nitrogen atmosphere by standard Schlenk techniques or in an M. Braun Labmaster glovebox. Glassware was dried at 150 °C overnight. Diethyl ether, n-pentane, tetrahydrofuran, and toluene, were purified by the Glass Contour solvent purification system. Deuterated benzene was first dried with CaH₂, then over Na/benzophenone, and then vacuum transfer into a storage container. Before use, an aliquot of each solvent was tested with a drop of sodium benzophenone ketyl in THF solution. All reagents were purchased from commercial vendors and used as received. Complex 1 was prepared according to a literature procedure.19 (link)¹H NMR data were recorded on a Varian Unity 400 MHz or a Varian Inova 500 MHz spectrometer at 25 °C.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
