Electric Literature of 87661-20-9, The chemical industry reduces the impact on the environment during synthesis 87661-20-9, name is tert-Butyl cyclopropanecarboxylate, I believe this compound will play a more active role in future production and life.
tert-Butyl 1-allylcyclopropanecarboxylate STR11 A solution of 34.1 g (0.24 mol) of tert-butyl cyclopropanecarboxylate in 25 ml of tetrahydrofuran was added dropwise at -70 C. to a mixture of 33.6 ml (0.24 mol) of diisopropylamine, 150 ml of a 1.5 molar solution of n-butyllithium in n-hexane (=0.24 mol of butyllithium) and 100 ml of tetrahydrofuran. Stirring was carried out for 3 hours at -70 C., after which a solution of 27.8 g (0.23 mol) of allyl bromide in 25 ml of tetrahydrofuran was added dropwise. Thereafter, the reaction mixture was stirred for a further 2 hours at -70 C. and then for 12 hours at 20 C. After hydrolysis with 50 ml of saturated aqueous ammonium chloride solution and after phase separation, the organic phase was worked up in a conventional manner to obtain the product. The crude product was purified by distillation. Yield: 61%, bp.: 86-88 C. at 30 mbar; colorless oil.
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 cyclopropanecarboxylate, other downstream synthetic routes, hurry up and to see.
