The reactions of bis(trimethylsilylmethyl)yttrium complexes
supported by bulky amidopyridinate (Ap) and amidinate (Amd) ligands
(LY(CH2SiMe3)2(THF)n: L = Ap, n = 1 (1); L = Amd, n = 1 (2)) with 2,6-diisopropylaniline and
phenylacetylene were performed. The reaction of 1 with
an equimolar amount of 2,6-diisopropylaniline occurs with TMS elimination
and affords an yttrium alkyl anilido species which was isolated as
a DME adduct, ApY(CH2SiMe3)(NH-2,6-iPr2C6H3)(DME) (3).
The protonolysis of 3 with phenylacetylene results in
the alkynyl anilido derivative ApY(CCPh)(NH-2,6-iPr2C6H3)(DME) (6).
The treatment of complexes 3 and 6 with
2,2′-bipy leads to the formation of the bis(anilido) derivative
ApY(NH-2,6-iPr2C6H3)2(bipy) (5). The formation of a dimeric
complex containing two ApY fragments linked by two μ2-alkynyl groups and a μ-η2:η2-butatrienediyl fragment, [{AmdY(μ2-CCPh)}2(μ2-η2:η2-PhCCCCPh)] (7), was observed in the reaction of 2 with 2 equiv of phenylacetylene.
