98298-66-9,Some common heterocyclic compound, 98298-66-9, name is 1-Chloroethyl isopropyl carbonate, molecular formula is C6H11ClO3, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
EXAMPLE 10 Preparation of 1-bromoethyl isopropyl carbonate A solution of 1-chloroethyl isopropyl carbonate (16.7 g; 0.10 mol) and hexabutylguanidinium chloride (0.43 g; 0.0011 mol) in toluene (40 ml) is heated to 115 C. and a gas stream containing 15 g (0.186 mol) of anhydrous hydrobromic acid is passed through it over 7 hours. The reaction medium is degassed with argon, the toluene is removed, the product is distilled under reduced pressure and 16.0 g of the expected product is obtained (Yld=76%).
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route 1-Chloroethyl isopropyl carbonate, its application will become more common.
