Thermodynamically preferred axial allylic –NHTs substituent in simple l-triisopropylsilyl(oxy) cyclohexenes: solid state conformation by X-ray crystallography
For a series of 6-(4-methylphenylsulphonyl)amino-1-triisopropylsilyl(oxy)-cyclohexenes the preferred conformation, in the solid state, has the –NHTs (Ts = 4-methylphenylsulphonyl) group in an axial orientation; if the axial-NHTs group experiences a 1,3-diaxial interaction with a methyl group, the equatorial conformation becomes the thermodynamically more stable form.
