WebUnder ordinary conditions, nitrogen is a colorless, odorless, and tasteless gas. It boils at 77 K and freezes at 63 K. Liquid nitrogen is a useful coolant because it is inexpensive and has a low boiling point. Nitrogen is very unreactive because of the very strong triple bond between the nitrogen atoms. WebAll procedures were conducted with using Schlenk techniques under nitrogen atmosphere. Styrene derivative and ENB were placed in a 50-ml flask, and then a nickel compound (2.5 × 10- 6 mol) and MAO (2.5 × 10- 3 mol) were sequentially charged into the flask. The reactions were carried out at room temperature for 24 h.After completion of the reaction, excess …
