Polymer-bound protoheme–mono-N-[3-(imidazol-1-yl)propyl]amide and –mono-N-[5-(2-methylimidazol-1-yl)pentyl]amide
Abstract
Poly(1-vinyl-2-pyrrolidone)-bound protoheme–mono-N-[3-(imidazol-1-yl)propyl]amide and –mono-N-[5-(2-methylimidazol-1-yl)pentyl]amide from oxygen adducts with life time of ca. 1 h in an aqueous medium cooled to –30 °C, but non-bound protoheme analogues do not form under the same conditions.
