tert-Butyl 4-(2-diazoacetyl)piperazine-1-carboxylate

Å. Kaupang, C. H. Görbitz and T. Hansen

Abstract: The title crystal structure, C₁₁H₁₈N₄O₃, is the first diazoacetamide in which the diazoacetyl group is attached to an N atom. The piperazine ring is in a chair form and hence the molecule has an extended conformation. Both ring N atoms are bonded in an essentially planar configuration with the sum of the C-N-C angles being 359.8 (2) and 357.7 (2)°. In the crystal structure, the O atom of the diazoacetyl group accepts two H atoms from C-H donors, thus generating chains of weak hydrogen-bonded R₂¹(7) rings.
