A mononuclear divalent ytterbium hydrido complex supported by a super-bulky scorpionate ligand

The first mononuclear divalent ytterbium hydride complex [(Tp Ad,iPr )Yb(H)(THF)] (Tp Ad,iPr = hydrotris(3-adamantyl-5-isopropyl-pyrazolyl)borate) ( 2 ) bearing a terminal hydrido ligand was obtained by hydrogenolysis of the benzyl precursor in hexane. Complex 2 exhibited two different reaction patt...

Description
Summary:The first mononuclear divalent ytterbium hydride complex [(Tp Ad,iPr )Yb(H)(THF)] (Tp Ad,iPr = hydrotris(3-adamantyl-5-isopropyl-pyrazolyl)borate) ( 2 ) bearing a terminal hydrido ligand was obtained by hydrogenolysis of the benzyl precursor in hexane. Complex 2 exhibited two different reaction patterns towards allenes: Yb-H addition with cyclohexylallene and deprotonation of 1,1-dimethylallene. The first mononuclear divalent ytterbium hydride complex [(Tp Ad,iPr )Yb(H)(THF)] (Tp Ad,iPr = hydrotris(3-adamantyl-5-isopropyl-pyrazolyl)borate) ( 2 ) bearing a terminal hydrido ligand was obtained by hydrogenolysis of the benzyl precursor in hexane.
