Crystal structure of 4-(prop-2-yn-yloxy)-2,2,6,6-tetra-methyl-piperidin-1-ox-yl.

ABSTRACT: The title compound, C12H20NO2, was synthesized from 4-hy-droxy-2,2,6,6-tetra-methyl-piperidin-1-oxyl (hy-droxy-TEMPO) and propargyl bromide. The six-membered ring adopts a flattened chair conformation and carries a propyn-yloxy substituent in an equatorial orientation at the 4-position. The N-O bond length of the piperidin-1-oxyl unit is 1.289 (3) Å. In the crystal, C-H⋯O hydrogen bonds combine with unusual C-H⋯π inter-actions involving the alkyne unit as acceptor to generate a three-dimensional network.
