cycloaddition reaction between c30 and hula-i, 3-diene was studied within the snimework of am i (rhf)level. the reaction involving the double bond between two hexagons and a hexagon and a pentagon, as wellas the cycloaddition products followed by disrotatory ogs s electrocyclic ring openings were considered.thermodynamics parameters and stability energy and innsation state are evaluated in thre...

A method for the metal-free synthesis of benzotriazoles in flow is reported. Using azides and situ generated arynes, are formed a [3+2] cycloaddition within minutes. Employing different substitution patterns azide aryne coupling partners, modular access to provided. Thermal strain hazardous accumulation reactive intermediates minimized by short reaction times flow, improving safety profile proc...
