Abstract

AbstractReaction of the hydrazinediido complex 1 with lithiated phenylacetylene selectively gave the lithium alkynyl(hydrazinediido)zirconate [(N2TBSNpy)Zr{μ‐NNPh2‐1κN:2κN}{μ‐PhCC‐1κC:2κC}‐Li(py)] (2), which reacted with one molar equivalent of TMEDA to give the corresponding Li‐TMEDA derivative [(N2TBSNpy)Zr{μ‐NNPh2‐1κN:2κN}{μ‐PhCC‐1κC:2κC}‐Li(TMEDA)] (3). The details of the molecular structure of complex 3 were established by single‐crystal X‐ray structure analysis. The lithium hydrazinediidozirconate 2 was treated with triethylammonium hydrochloride yielding the corresponding alkinylzirconium hydrazido(1‐) complex 4 as a mixture of two diastereomers.
