Abstract
Reactions of chromium(II) aminocarboxylate complexes (ethyleriediamine-tetr aacetate, nitrilo-triacetate, imino-diacetate) with acetylated glycopyranos yl chlorides or bromides in liquid-liquid or solid-liquid biphasic media (s uch as water-diethylether, water-ethyl acetate or halosugar-water) give the corresponding glycals in 75-97% yield.
