Synthesis and crystal structures of N-Aryl-N-methylaminocyclohexanols

Abstract

N-Aryl-N-methylaminocyclohexanols 10-12 were synthesised and their crystal structures were studied by X-ray diffraction. Compound 10 crystallizes in the monoclinic space group Cc with cell parameters of a = 13.7366(2) Å, b = 13.7234(2) Å, c = 26.9057(5) Å, β = 93.0900(5), V = 5064.70(14) Å3 and Z = 16. Compound 11 crystallizes in the trigonal space group P 3 ̄ with cell parameters of a = b = 25.4429(4) Å, c = 9.6417(2) Å, V = 5405.27(16) Å3 and Z = 18. Compound 12 crystallizes in the monoclinic space group P21/n with cell parameters of a = 9.9511(2) Å, b = 11.5777(2) Å, c = 20.5968(4) Å, β = 95.5037(9), V = 2362.04(8) Å3 and Z = 8. All three structures were characterised by arrays of hydrogen bonding interactions and these crystallographic studies revealed conformations of 10-12 which gave valuable information into the mechanism of the reaction during their formation.
