Abstract:
An easily-accessible neutral scandium complex Sc[OC(CH3)2CH2PPh2][O-2,6-tBu2-C6H3]2[THF] behaves as a reactive Sc/P frustrated Lewis pair, which when added to organic and inorganic substrates e.g. carbonyl compounds, transition-metal chlorides, and diazoalkane compounds, yields unique and intriguing addition products such as a Sc/Rh heterobimetallic complex and a Sc phosphazine complex.
