The reaction of the yttrium dialkyls (C5H4–PPh2N–C6H3iPr2)Y(CH2SiMe3)2(thf) (1) with an excess
of N,N′-diisopropylcarbodiimide
gave
the yttrium monoalkyl complex (C5H4–PPh2N–C6H3iPr2)Y(CH2SiMe3)[iPrNC(CH2SiMe3)–NiPr] (2). 2 subsequently
reacted with 1 equiv of PhSiH3 to generate the CpPN/amidinate
heteroleptic yttrium hydride {(C5H4–PPh2N–C6H3iPr2)Y[iPrNC(CH2SiMe3)–NiPr](μ-H)}2 (3). Hydride 3 showed good reactivity
toward various substrates containing unsaturated C–C, C–N,
and N–N bonds, such as azobenzene, p-tolyacetylene,
1,4-bis(trimethylsilyl)-1,3-butanediyne, N,N′-diisopropylcarbodiimide, and 4-dimethylaminopyridine,
affording the yttrium hydrazide complex 4 with a rare
η2-Cp bonding mode, yttrium terminal alkynyl complex 5, yttrium η3-propargyl complex 6, yttrium amidinate complex 7, and yttrium 2-hydro-4-dimethylaminopyridyl
product 8, respectively.
