Calcium Carbene Complexes

(Orzechowski, Jansen, Harder  J. Am. Chem. Soc. 2006)         (Orzechowski, Harder  Organometallics 2007)

The first calcium carbene complexes with a formal electrostatic "double bond" between a R₂C^2- unit and Ca²⁺ have been obtained in the form of a bis(iminophosphorane)-methandiide complex.

Substitution of the Me₃Si-substituent for the much larger 2, 6-diisopropylphenyl group results in formation of a monomeric calcium carbene complex.
