Abstract
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(C≡CPh)(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-C≡CPh)}2(μ2-η2:η2-PhCCCCPh)] (7), was observed in the reaction of 2 with 2 equiv of phenylacetylene.
