Heavy-Atom Tunneling {in the|within the|inside the} Covalent/Dative Bond Complexation of Cyclo[18]carbon–piperidine
{Recent|Current} quantum chemical computations demonstrated the electron-acceptance behavior of this {highly|extremely|very|hugely} reactive cyclocarbon (C18) ring with piperidine (pip). The C18–pip complexation exhibited a double-well {potential|possible|prospective} along the N–C reaction coordinate,…
