Nuclear magnetic resonance evidence for bridge hydrogen tautomerization (and/or exchange) in monocarbahexaborane(7)
Abstract
Temperature studies on monocarbahexaborane(7) show that the two high field doublets in the 11B n.m.r. spectrum taken at 30° collapse into a single doublet at 100°: possible mechanisms are suggested to account for this observation; all involve migration of the single bridge hydrogen.
