Crystal structure of 2-(2,6-diiso­propyl­phen­yl)-N,N-diethyl-3,3-dimethyl-2-aza­spiro­[4.5]decan-1-amine: a di­ethyl­amine adduct of a cyclic(alk­yl)(amino)­carbene (CAAC)

The structure of the title compound, C(27)H(46)N(2), at 93 K has monoclinic (P2(1)/n) symmetry. The title compound was prepared by treatment of 2-(2,6-diiso­propyl­phenyl)-3,3-dimethyl-2-aza­spiro­[4.5]dec-1-en-2-ium hydrogen dichloride with two equivalents of lithium di­ethyl­amide. Characterizatio...

Sumario:The structure of the title compound, C(27)H(46)N(2), at 93 K has monoclinic (P2(1)/n) symmetry. The title compound was prepared by treatment of 2-(2,6-diiso­propyl­phenyl)-3,3-dimethyl-2-aza­spiro­[4.5]dec-1-en-2-ium hydrogen dichloride with two equivalents of lithium di­ethyl­amide. Characterization of the title compound by single-crystal X-ray diffraction and (1)H and (13)C NMR spectroscopy is presented. Formation of the di­ethyl­amine adduct of the cyclic(alk­yl)(amino)­carbene (CAAC) was unexpected, as deprotonation using lithium diiso­propyl­amide results in free CAAC formation.
