768-66-1,768-66-1, 2,2,6,6-Tetramethylpiperidine is a piperidines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
“BuLi (1.6 M solution in hexanes, 11.3 ml_) was added dropwise over 15 min to a solution of 2,2,6,6-tetramethylpiperidine (TMPH) (3.0 mL, 18 mmol) in 20 ml_ of hexanes at 0 C. After addition, formation of white precipitate was observed. The resulting mixture was stirred at 0 C for 30 min, warmed up to room temperature and stirred for additional 1 h. All volatiles were pumped off. The product was precipitated from pentane (30 mL) at -30 C, filtered off and dried in vacuum (1.48 g, 56%). 1H NMR (400 MHz; THF-d8; delta, ppm): 1.07 (br s, 12H); 1.20 (br m, 4H); 1.65 (br m, 2H). 3C{1H} NMR (100.6 MHz; THF-d8; delta, ppm): 36.4 (br s); 42.9 (br s); /joso-carbon and one CH2 were not observed due to broadening. 7Li NMR (155.5 MHz; THF-de; delta, ppm): -0.5 (br s).
As the paragraph descriping shows that 768-66-1 is playing an increasingly important role.
