The glassware was flame dried under Ar or N2 gas and assembled with a magnetic bar, stirrer, and septum. THF was distilled over CaH and dried over Na and benzophenone before use. Hexane, ether, and ethyl acetate were purified using simple distillation. DMI and other reagents were purchased from Aldrich and Acros Organics. All reactions were analyzed by 1H NMR (300, 400, or 700 MHz) and 13C NMR (75, 100, or 176 MHz) using a Bruker DPX-300, Bruker Advance DRX-400, or Bruker Ascend Aeon 700 spectrometer. The samples were dissolved in 99.8% chloroform-d (CDCl3), and the solvent signals at 7.26 (1H) and 77.0 (13C) ppm were used as internal standards for hydrogen and carbon, respectively. The IR spectra were measured either on a Bruker Tensor 27 FT-IR spectrometer or a Thermo Nicolet 1S5.

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.
