Abstract
This article reports a practical synthesis of tert-butyl acetyl-carbamate, C7H13NO3, from N-Boc-thio-acetamide and the study of its crystal structure. The reaction proceeds in the presence of natural phosphate as a catalyst, with excellent yield, simple workup and benign environment. The crystal structure was refined using a transferred multipolar atom model. In the crystal, symmetrical pairs of strong N-H⋯O hydrogen bonds connect the mol-ecules into dimers with an R 2 2(8) ring motif. The inter-actions between neighbouring dimers are mostly van der Waals, between hydro-phobic methyl groups. Hirshfeld surface analysis shows the major contributions to the crystal packing are from H⋯H (42.6%) and O⋯H (26.7%) contacts.
