Oxorhenium(V)-mediated synthesis and structures of oxypyridinium-ammonium zwitterions
Oxorhenium(V)-mediated synthesis and structures of oxypyridinium-ammonium zwitterions
Treatment of N,N -bis(2-hydroxybenzyl)-2-(2-aminoethyl)dimethylamine (H2 had) with trans-[ReO2 (py) 4 ]I in acetone affords the iodide salts of the oxypyridinium-ammonium zwitterions N1 -(2-hydroxybenzyl)- N2 ,N2 -dimethyl-N1 -((2-oxypyridinium)-1-methyl)ethane-1,2-diamine [Hhpd]+ and N2 ,N2 -dimethyl-N1 - bis((2-oxypyridinium)-1-methyl)ethane-1,2-diamine [dod]+ . The products were characterized by X-ray structure analysis, and NMR and IR spectroscopy.
