Metal-assisted reactions. Part 26.1 Catalytic reactivity and ether bond lengths in aryloxytetrazoles and aryloxypseudosaccharins

Abstract

X-Ray structure determinations on a variety of aryloxytetrazoles 1 and aryloxypseudosaccharins 4 have shown that the central C–O–C ether linkage is remarkable in having one very long C–O bond and one very short one. The central C–O–C bond angle is close to 120°. The implications of these effects on the reactivity of compounds 1 and 4 towards catalytic hydrogenolysis or cross-coupling are explored.
