The novel dimeric bis(2,4,7-trimethylindenyl)yttrium hydride
[(Ind‘)<sub>2</sub>Y(μ-H)]<sub>2</sub> (<b>3</b>) has
been prepared
from
(Ind‘)<sub>2</sub>Y(μ-Cl)<sub>2</sub>Li(THF)<sub>2</sub>
(<b>1</b>) via the alkyl complex
(Ind‘)<i><sub>2</sub></i>YCH(SiMe<sub>3</sub>)<sub>2</sub>
(<b>2</b>). The hydride <b>3</b> is a catalyst
that
effects the regio- and stereoselective homodimerization
of a range of α-olefins at 80 °C as well as
head-to-head
codimerization of styrene with other α-olefins.
