acme: an international journal of critical geographies is an international journal for critical analyses of the social, the spatial, the ecological, and the political, grounded in critical geographic scholarship. we recognize that the scholarship we publish takes place on indigenous territories across the globe, and that the geographies represented in acme are themselves formed through imperialism and colonialism. there is diversity in the lands, waters, and indigenous nations on whose territories we depend. as a journal of geography, we also acknowledge the imperial and colonial roots of the discipline, and we seek to publish scholarship in solidarity with global and localized struggles.

Benzothiazole-based thiourea and urea derivatives are heterocycles of significant biological and pharmaceutical relevance. Understanding their formation pathways is essential for predicting reactivity and stability. In this work, Density Functional Theory (DFT) calculations were employed to investigate the thermodynamic and kinetic aspects of two competing condensations: 2-aminobenzothiazole with phenyl isothiocyanate (thiourea derivative) and with phenyl isocyanate (urea derivative). Geometrical, electronic, and energetic parameters were evaluated using the B3LYP functional with the 6-31G(d,p) and 6-311++G(d,p) basis sets in the gas phase, acetonitrile (ACN), and the ionic liquid ethyl pyridinium iodide ([EPy]I). The results indicate that Reaction II (urea formation) is both kinetically and thermodynamically favorable in all environments, whereas Reaction I becomes nearly thermoneutral or slightly endergonic with the larger basis set, especially in [EPy]I. IRC analysis further reveals a concerted addition–proton-transfer mechanism for both pathways, providing direct mechanistic insight. Solvent effects, particularly in acetonitrile, further enhance charge polarization and stabilize the corresponding transition states, strengthening the preference for the urea pathway. These findings provide mechanistic insights into benzothiazole reactivity and may guide future synthetic optimization.
