One interesting method utilizes tertiary N-oxides to essentially “oxidize off” a CO ligand, leaving behind an open coordination site that may be filled by a phosphine. WebLigand 1 contains a resorcin [4]arene 24,25 macrocycle comprised of four phosphate substituted aromatic units. The macrocycle shows some degree of flexibility, as the structure rapidly interconverts between two equivalent boat conformations, but full rotation is prevented through its alkyl feet (Fig. S18–S20, ESI † ). dyson dc24 ball not rolling
