Interactions and reactions in some 2,2'-disubstituted biphenyls--an open or shut case
1School of Science and Technology, Nottingham Trent University, Clifton Lane, Nottingham, UK.
Abstract:
2-Dimethylaminobiphenyls bearing an electron deficient alkene in the 2' position show either Me2N...C=C interactions (2.941-2.976 A) or form a new N-C bond (1.586-1.604 A) to give a zwitterion. The former provides a model for an intermolecular interaction, while the latter provides structural information on organic anionic systems uncoordinated by metal cations.
