The reaction of the yttrium dialkyls (C5H4-PPh 2=N-C6H3iPr2)Y(CH 2SiMe3)2(thf) (1) with an excess of N,N′-diisopropylcarbodiimide gave the yttrium monoalkyl complex (C 5H4-PPh2=N-C6H3 iPr2)Y(CH2SiMe3)[ iPrN=C(CH2SiMe3)-NiPr] (2). 2 subsequently reacted with 1 equiv of PhSiH3 to generate the CpPN/amidinate heteroleptic yttrium hydride {(C5H4- PPh2=N-C6H3iPr2)Y[ iPrN=C(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.
