T. Moriguchi et al., Evaluation of transannular interaction of [2.3] metacyclophane-diazonium tetrafluoroborate and its dediazoniated derivatives, J CHEM R-S, (2), 1999, pp. 78-79A
Transannular interactions of [2,3] metacyclophane-diazonium tetrafluorobora
te and its dediazoniated derivatives have been evaluated by H-1 NMR, IR, UV
and stability constant determination.
