SmCp2, which is easily prepared from SmI2, has been screened as a reducing agent for organic chemistry. In particular, SmCp2 promotes the pseudo-Barbier reaction between carbonylcompounds (aldehydes and ketones) and aliphatic or allylic halides more efficiently than does SmI2.

Titaniumtetrakis(dialkylamides) are chemoselective protective agents for carbonyl compounds, so that such reactions as Grignard and aldol additions can be induced to occur at ketone groups in the presence of aldehydes in a one-pot procedure.

Enantiomerically pure phosphoroselenoyl chloride bearing a binaphthyl group was synthesized. This phosphoroselenoyl chloride was used to discriminate and resolve simple secondary alcohols. Stereospecific conversions of diastereomerically pure phosphoroselenoic acid esters, obtained by reaction of the chloride with simple secondary alcohols, to enantiomerically purealcohols and amines were also achieved

electron-deficient π-conjugated systems are key building units for semiconductingpolymers that are used in organic electronic devices, such as organic photovoltaic (OPV) cells. Here, we designed and synthesized a naphthobispyrazine derivative bearing four ester groups (eNPz) as a new electron-deficient building unit and three eNPz-based semiconductingpolymers with different donor units, that is, bithiophene (PeNPz2T)
