Methyl coumalate readily reacts with enamines at ambient temperature to give lactones, which can be further transformed into isophthalates and tetrahydronaphthoates. Both cyclic and acyclic enamines show good reactivity. Dehydrogenation of tetrahydronaphthoate 4a was achieved on a hundred-gram scale.
Preparation method of cationic polymerization bifunctional initiator and telechelic polyisobutene

Paragraph 0024, (2017/09/18)
The invention discloses a preparation method of a novel cationic polymerization bifunctional initiator. The initiator is produced to a kilo grade scale meeting industrial production from a laboratory gram-grade scale, so that the synthetic cost of the initiator is greatly lowered. By developing a series of novel initiator derivatives, the brand new initiator which is higher in initiating efficiency, lower in energy consumption and higher in production efficiency are found, and telechelic polyisobutene, the functional groups (hydroxyl, double bonds or chlorine group) of which are fully terminated and the molecular structure of which is controllable, can be synthesized.
