Isolation and Characterization of Carbene Derivatives of La@C82(C s )

Isolation and Characterization of Carbene Derivatives of La@C82(C s )

The photochemical reaction of La@C82(C s ) with 2-adamantane-2,3-[3H]-diazirine (1) affords the adduct 2 of La@C82(C s ) with adamantylidene (Ad:) in a high selectivity. The two isomers of La@C82(C s )(Ad), 2a and 2b, are isolated by HPLC and characterized by electron spin resonance, mass, and UV−vi...

Zusammenfassung:The photochemical reaction of La@C82(C s ) with 2-adamantane-2,3-[3H]-diazirine (1) affords the adduct 2 of La@C82(C s ) with adamantylidene (Ad:) in a high selectivity. The two isomers of La@C82(C s )(Ad), 2a and 2b, are isolated by HPLC and characterized by electron spin resonance, mass, and UV−vis−near-infrared spectroscopies. The electronic properties of 2a and 2b are very similar to that of the pristine La@C82(C s ), suggesting that 2a and 2b retain the essential electronic and structural character of La@C82(C s ).
