Crystal Structure Analysis of a trans, trans‐Cyclodeca‐1, 6‐diene Derivative
White DNJ.
AbstractAn X‐ray crystal structure analysis of the higher melting diastereoisomer of 2,7‐dibromo‐3,8‐dimethoxy‐trans,trans‐cyclodeca‐1,6‐diene (Monoclinic; a = 5.76, b = 10.43, c = 11.32 Å, β = 94.04°; space group P21/n; Z = 2) has confirmed the NMR. assignment of the molecular conformation and the trans configuration of the methoxy groups. The trans,trans‐cyclodeca‐1,6‐diene ring adopts a centrosymmetric crown conformation with a CCCC torsion angle of 162°.
