WebApr 30, 2011 · Abstract. The cis- and trans-2-methyl-2-oxo-2-trityl-1,3,2-dioxaphosphorinanes were obtained in the Arbuzov reaction of 2-methoxy-4-methyl-1,3,2-dioxaphosphorinane with trityl chloride.The NMR spectra (1 H, 13 C and 31 P) in solution indicated that trans isomer exists in the form of two noncongruent molecules and it adopts two different … WebThe peak for the hydrogen-alkene bond should have been significantly bigger due to the fact that there are 15 hydrogen-alkene bonds within trityl methyl ether. The NMR also showed …

WebWhen 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene (IDipp, 1a) was allowed to react with the trityl salt in toluene at −40 °C, we observed the clean formation of adduct 2a . The structure of 2a was established by NMR spectroscopy and by single crystal X-ray diffraction (XRD) analysis (see the ESI†).
