일반 설명
β-Butyrolactone undergoes ring opening polymerization in the presence of ethoxy-bridged dinuclear indium catalyst to yield biodegradable polyester poly(hydroxybutyrate). Polymerization of racemic β-butyrolactone in the presence of chiral initiators has been reported. It is versatile building block for organic synthesis.
애플리케이션
β-Butyrolactone was used in the preparation of (3-O-[oligo-(3-hydroxybutyrate ester)] fluorescein, fluorescein derivative of poly(3-hydroxybutyrate) via anionic polymerization.

The mechanism of the ring-opening polymerisation of beta-butyrolactones was studied. The ring-opening polymerisation of BL catatlysed by distannoxane complexes is of a living nature. The polymerisation of racemic BL gave a predominantly syndiotactic P(3HB). The temperature effect on syndiospecificity was

A new heteroleptic ethyl-zinc complex stabilized by a chelating bis(morpholinomethyl)phenoxy ligand has been synthesised and shown to be a highly potent initiator for the immortal ring-opening polymerisation (ROP) of lactide and beta-butyrolactone, being able to convert up to 50,000 equiv.

Novel feasibility of fuctionalized poly(3-hydroxybutanoic acid), PHB, and its copolymers synthesis via ring-opening of beta-butyrolactone (ROP) mediated by activated anionic initiators or enzymes in vitro is presented. Using these new synthetic approaches, PHB with defined chemical structure of the end

A series of new yttrium complexes supported by the bulky enediamido dianionic ligand DAB(2-) (DAB(2-) = (2,6-C(6)H(3)iPr(2))NC(Me)=C(Me)N(2,6-C(6)H(3)iPr(2))(2-)), that is, {DAB}Y(THF)(2)(mu-Cl)(2)Li(THF)(2) (1), {DAB}Y(OtBu)(THF)(DME) (2), and {{DAB}Y(BH(4))(2)}{Li(DME)(3)} (3), was synthesized by salt metathesis. The complexes were isolated after recrystallization in 73, 66
