Crystal structure of 4-(prop-2-yn­yloxy)-2,2,6,6-tetra­methyl­piperidin-1-ox­yl

The title compound, C(12)H(20)NO(2), was synthesized from 4-hy­droxy-2,2,6,6-tetra­methyl­piperidin-1-oxyl (hy­droxy-TEMPO) and propargyl bromide. The six-membered ring adopts a flattened chair conformation and carries a propyn­yloxy substituent in an equatorial orientation at the 4-position. The N—...

Sumario:The title compound, C(12)H(20)NO(2), was synthesized from 4-hy­droxy-2,2,6,6-tetra­methyl­piperidin-1-oxyl (hy­droxy-TEMPO) and propargyl bromide. The six-membered ring adopts a flattened chair conformation and carries a propyn­yloxy 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 inter­actions involving the alkyne unit as acceptor to generate a three-dimensional network.
