General description

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.

Application

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.
