Abstract
Abstract The conformers of trimethylsilyl- N , N -diisopropyl carbamate were studied by 1 H NMR spectroscopy. The barriers to rotation by isopropyl groups and to the rotation around the amide bond, and the population of the conformers were determined from the coalescence temperature of the methyne signal. Single crystal X-ray diffraction studies revealed that the crystal had formed from preferred conformer in solution. The mirror symmetric conformer is stabilized by an intramolecular CH ⋯ O hydrogen bond and by an intramolecular O ⋯ Si donor-acceptor interaction.
