Immobilized enzymes are finding use in bioreactors for a wide range of applications such as in research, medicine, and industry. One of the greatest benefits of immobilized enzymes is that the enzymes can be used repeatedly. In this study, we encapsulated the hyperthermophilic β-glucosidase from Pyrococcus furiosus(BGLPf) into silica microcapsules. BGLPf plays an important role in the high-temperature hydrolysis of cellooligosaccharides found in biomass. This technology provides a new tool for the effective saccharification of biomass.

The combination of Ph4SbI and Bu3SnI proved to be a new excellent catalyst for effecting cycloaddition reaction of inactive 2,3-disubstituted oxiranes with isocyanates under neutral conditions, yielding oxazolidinones in high yields, while either of both metal iodides had no activity individually.

Azilidine–trimethylsilyl bromide–tetraphenylstibonium bromide system is an effective reagent to produce silyl enol ethers from cyclic ketones. This had the specific selectivity to silylate cyclic ketones exclusively even in the case of coexsisting with acyclic ketones.

Selective C-alkylation of 2-methyl-1,3-cyclopentanedione and 2-methyl-1,3-cyclohexanedione was performed by using tetraphenylstibonium methoxide (Ph4SbOMe). The presence of a substituent at the 2-position was essential for C-alkylation.
