Application
1-Methyl-2-pyrrolidinone may be used as a solvent in the following processes:
- Preparation of 2-aryl and 2-alkyl benzothiazoles.
- Ullmann coupling reaction of aryl halides and phenols to form Ullmann ethers in the presence of 2,2,6,6-tetramethylheptane-3,5-dione.
- Stille cross-coupling reaction of aryl iodides with organostannanes catalyzed by Pd/C in the presence of copper iodide as cocatalyst.

Black phosphorus is a two-dimensional material of great interest, in part because of its high carrier mobility and thickness dependent direct bandgap. However, its instability under ambient conditions limits material deposition options for device fabrication. Here we show a black
