Complexation of Bis(trimethylsilyl)acetylene by Decamethylhafnocene To Give the Hafnacyclopropene Cp2Hf(η2-Me3SiC2SiMe3):  An Unusually Strong Metal−Alkyne Interaction

The complexes Cp2Hf(PMe3)(η2-Me3SiC2SiMe3) (3) and Cp*2Hf(η2-Me3SiC2SiMe3) (4), as the first examples of well-defined hafnium alkyne complexes with a simple intact alkyne, are described; 4 displays an unusually strong interaction of the alkyne with hafnium, in comparison to analogous compounds of ti...

Summary:The complexes Cp2Hf(PMe3)(η2-Me3SiC2SiMe3) (3) and Cp*2Hf(η2-Me3SiC2SiMe3) (4), as the first examples of well-defined hafnium alkyne complexes with a simple intact alkyne, are described; 4 displays an unusually strong interaction of the alkyne with hafnium, in comparison to analogous compounds of titanium and zirconium.
