Description
при этом в качестве исходных монозамещенных олефинов используют или свободные av-олефины или а-олефины, содержащие функциональную , например карбоксильную группу. В данном случае присоединение у-бутиролактона происходит у а-углеродного атома. При мол рном соотнощении у-бутиролактон: а-олефин: перекись 20 : 1 : 0,25 получают а-алкил-у-бутиролактон с выходом 60-70Vo.in this case, either free av-olefins or a-olefins containing a functional, for example, carboxyl group are used as the starting monosubstituted olefins. In this case, the y-butyrolactone is attached at the a-carbon atom. At the molar ratio of y-butyrolactone: a-olefin: peroxide 20: 1: 0.25, a-alkyl-y-butyrolactone is obtained with a yield of 60-70Vo.
Помимо а-олефинов в реакции с v-бутиролактоном могут быть использованы непредельные функциональные соединени с концевым положением кратной св зи.In addition to α-olefins, unsaturated functional compounds with the terminal position of a multiple bond can be used in the reaction with v-butyrolactone.
Пример 1. Синтез а-децил-у-бутиролактона.Example 1. Synthesis of a-decyl-y-butyrolactone.
