Electric Literature of 6627-89-0, The chemical industry reduces the impact on the environment during synthesis 6627-89-0, name is tert-Butyl phenyl carbonate, I believe this compound will play a more active role in future production and life.
EXAMPLE 4 Synthesis of Tert-butyl N-(3-trimethoxysilylpropyl) carbamate Into a 3-neck round bottom flask equipped with a thermometer, dropping funnel and a nitrogen line, was added tert-butyl phenyl carbonate (9.71 gms., 0.050 moles) and dimethyl formamide (10 gms.). 3-Aminopropyltrimethoxysilane (8.61 gms., 0.048 moles) was slowly added at 25 C. with stirring. An exotherm raised the temperature to 32 C. The reaction was stirred at room temperature for 24 hours. A GC showed the formation of a new peak with retention time 16.30 min. (3-aminopropyltrimethoxysilane had a retention time of 12.26 min., phenol had a retention time of 8.01 min., tert-butyl phenyl carbonate had a retention time of 12.84 min. and tert-butyl alcohol had a retention time of 2.44 min.; GC conditions were OV 101 on Chromasorb W-HP 1/8″*6′, 50 C. initial temperature, program rate of 10 C./minute, final temperature of 295 C.). The reaction mixture stood for an additional 3 days. The dimethyl formamide was removed by rotovap at 5 mm Hg at 50 C. A clear liquid (10.16 gms) was collected. It dissolved in n-hexane (25 gms) and extracted twice wih a 5% sodium carbonate solution that was cooled to 5 C. The organic layer was isolated and dried over magnesium sulfate. The n-hexane was removed on a rotovap to yield 4.47 gms of an oil. 1-H NMR indicated only the presence of phenol and 3-aminopropyltrimethoxysilane confirming that a blocked carbamate silicon compound was formed and decomposed during work-up.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, tert-Butyl phenyl carbonate, other downstream synthetic routes, hurry up and to see.
