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
EXAMPLE 1 [0038] 95.4 g THF and 14.61 g (103 mmol) 2,2,6,6,-tetramethylpiperidine were placed in a 500-mL double-jacketed reactor. The temperature was set at 20 C. 6.82 g n-butyllithium concentrate (95.5%, 99 mmol) was metered in via a dosing pump over a period of 30 minutes. The jacket temperature of the reactor was regulated so that the internal temperature remained constant at 20 C. Stirring was then continued for an additional 10 minutes at 20 C. 14.14 g (104 mmol) solid zinc chloride was then added in two portions. Due to the strongly exothermic reaction, the reaction temperature quickly rose to 30 C. After the second addition of ZnCl2, stirring was continued for an additional 20 minutes at 20 C. [0039] The cloudy product solution was filtered through a filter until clear. The cloudy product solution was filtered through a filter until clear. [0040] Starting weight: 128.6 g [0041] Active base: 0.62 mmol/g TMP-ZnCl*LiCl [0042] Yield: 80.5% (relative to n-butyllithium used), 768-66-1
As the paragraph descriping shows that 768-66-1 is playing an increasingly important role.
