in ethanol

acetic acid in acetic acid Kinetics; stannane was added to AcOH in a NMR tube, mixt. was kept for 21 d, reaction followed by (1)H NMR spectroscopy; ca. 34percent of the substrate was consumed, rate const. for the initial 5-10percent reaction (first 2 d) when only Me3SnOAc was formed; not isolated, identified by (1)H NMR spectrum;

acetic acid in acetic acid Kinetics; byproducts: Me3SiOAc, Me3SiOSiMe3; stannane was added to AcOH in a NMR tube, mixt. was kept for 21 d, reaction followed by (1)H NMR spectroscopy; ca. 39percent of the substrate was consumed, rate const. for the initial 5-10percent reaction (first 2 d) when only Me3SnOAc and Me3SiOAc were formed; not isolated, identified by (1)H NMR spectrum;
