Abstract

Ni(C₂H₄)₃ reacts with alkalimetal hydridoaluminates or -gallates M_AHAl/GaR₃ and M_AH₂AlR₂ (R= alkyl) in ether/pmdta at temperatures between −70 and −20°C to yield the ion pair complexes (pmdta)M_A(μ₃-H)Ni₂(C₂H₄)₂ (M_A = Li (2a), Na (2b)). According to their structure and chemical properties, 2a,b can be regarded as model compounds for the nickel(0) induced addition of alkalimetal hydrides to alkenes.
