| Abstract: | Rh(I)-catalysed [2 + 2 + 2] cycloaddition allows the synthesis of aryl ethers and diaryl methanes containing a high degree of steric hindrance from relatively simple diyne and alkyne precursors. The diarylmethanes made in this way show no evidence in their NMR spectra, however, of rotational restriction. |
