Heteronuclear correlation spectroscopy reactions

The hydroformylation of an unsaturated steroid proceeded in high chemo-, diastereo-, and regioselectivity (Scheme 14.9) with diastereoselectivity assigned by correlation spectroscopy (COSY), and heteronuclear correlation spectroscopy (HETCOR) spectra." This reaction of this trisubstituted alkene used a [Rh(nbd)Cl]2 precursor (nbd) and P( -Bu)3 as a ligand, at 120°C and pressures of 100-120 bar. [Pg.402]

Nuclear Overhauser effect (NOE) difference measurements were used to assign structure 79 for the product of reaction of diphenylnitrile imine with 5-ethylsulfonyl-2-methyl(27/)pyridazinone. Thus in the H NMR spectrum the ot/, o-protons of the arylhydrazino moiety (which were identified by two-dimensional heteronuclear multiple quantum correlation (2-D HMQC) spectroscopy) were shown in differential NOE (DNOE) experiment to be significantly enhanced on irradiation of pyridazine hydrogen H-7, proving their steric proximity <2000JST13>. [Pg.607]
