AI Article Synopsis

  • The three-component nanorotor [Cu2(S)(R)]2+ is an effective catalyst for the CuAAC reaction, with a reaction rate of 46.0 kHz.
  • This nanorotor binds the resulting product at its copper sites, leading to the formation of a new and dynamic system.
  • The sliding motion of the rotor, which occurs at a rate of 65.0 kHz, allows for the efficient release of N-methylpyrrolidine, enabling it to catalyze a subsequent Michael addition.

Article Abstract

The three-component nanorotor [Cu2(S)(R)]2+ (k298 = 46.0 kHz) that is a catalyst for a CuAAC reaction binds the click product at each of its copper centers thereby creating a new platform and a dynamic slider-on-deck system. Due to this sliding motion (k298 = 65.0 kHz) the zinc-porphyrin bound N-methylpyrrolidine is efficiently released into solution and catalyzes a follow-up Michael addition.
