Preparation and pyrolysis of tetramethyltetrazene–beryllium dialkyl complexes

Abstract

The reactions of Me₂NNNNMe₂ with Et₂Be,Prⁱ₂Be, and Bu^t₂Be yielded 1:1 dative-bonded complexes and complexes with two beryllium alkyls per tetramethyltetrazene, the latter being more stable.

Pyrolysis of the 2:1 compounds near 200°C has resulted in the formation of low molecular weight polymers containing BeH and RBe, perhaps serving as bridging groups, and Me₂NNNNMe₂ apparently serving as a linking agent for the beryllium atoms.
