Intermolecular <i>head-to-head</i> interaction of carbonyl groups in bicyclic hydrogen-bonded synthon based on β-hydroxy ketones

Abstract

In this study, we report a counterintuitive carbonyl–carbonyl interaction explored for crystalline (2<italic>RS</italic>,3<italic>RS</italic>)-1-aryl-2-bromo-3-hydroxy-3-(2-nitrophenyl)-propan-1-ones.
