All
the chemical precursors,
namely, 4-iodoanisole, 4-nitroaniline, Cu powder, K2CO3, 18-Crown-6, Pd/C (10%), KOH, 1,10-phenanthroline, CuI, and
phenothiazine, as well as the solvents, were purchased form Sigma-Aldrich
and used without further purification. Compound 3 and 4 were synthesized according to previously reported methods.56 (link),57 (link) All the reactions were carried out under an inert environment in
Schleck tube. 1H and 13C NMR spectra were recorded
with 500 MHz JEOL spectrometer in CDCl3 against tetramethylsilane
as reference. Mass spectroscopy was carried out using a high-resolution
ESI-TOF LCT Premier XE mass spectrometer (Waters Corp.). The analyte
was dissolved in chloroform/methanol (c
0.01 mg/mL). More details on the synthesis are in the Supporting Information.

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.
