Abstract:

Frustrated Lewis pairs(FLPs) are combinations of bulky Lewis acids and bulky Lewis bases in solution that are deterred to from dative bonds by steric factors. In this particular combination, Lewis acids and Lewis bases failed to be neutralized and quenched, and remained reactive. When small molecules such as H2 are close to them, FLPs can split the chemical bonds of H2 to obtain a cation and an anion. This particular reaction activity shows promising applications of FLPs in catalytic hydrogenation, activation of small molecules, olefin polymerization, ring-opening polymerization and so on. Especially, in olefin polymerization and ring-opening polymerization, FLPs have a strong catalytic activity. In this article, we briefly introduce the development history of FLPs and the application of FLPs in activation of small molecules. In addition, the applications of FLPs in polymer fields are emphatically described.

Key words: frustrated Lewis pairs, catalyst, polymerization, activation of small molecules
