Reactions that
required inert conditions
were performed using modified Schlenk techniques or in an MBraun Unilab
glovebox under a nitrogen atmosphere. 1H and 13C NMR spectra were recorded on a Varian Unity Inova 400 MHz spectrometer. 1H and 13C NMR chemical shifts are given relative
to the residual proton or 13C solvent resonances. NMR spectra
were recorded at room temperature (20–25 °C) unless otherwise
noted. GC/MS data were collected on an Agilent 6890 Series GC connected
to a HP 5973 mass detector. Elemental analyses were performed using
a Thermo Electron Flash EA 1112 Series analyzer. Microwave heating
was conducted using a CEM Discover SP instrument in either 10 or 35
mL snap cap pressure tubes or in an open vessel mode. The temperature
of the reactions in the microwave was monitored using the floor-mounted
IR sensor in the instrument (external surface measurement).

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.
