资源简介：
We report the first structurally characterized terminal Ce(III) acetylide complex, Na[Ce(CCPh)(bdmmp)3] (2), isolated from the salt metathesis of NaCCPh with Na[Ce(OTf)(bdmmp)3] (1; bdmmp– = 2,6-bis(dimethylamino)-4-methylphenolate). Compound 2 inserted acetophenone to form the tertiary alkoxide complex Na[Ce(OC(Me)(Ph)CCPh)(bdmmp)3] (4), rather than forming an enolate product. To the best of our knowledge, complexes 2 and 4 are the first structurally characterized products that exhibit carbonyl group insertion into a Ce–C bond, affording new information on an important class of organocerium reagents.
