Rja. Janssen et al., SYNTHESIS AND CRYSTAL-STRUCTURE OF A NEW LARGE CRYPTAND ENCAPSULATINGA BENZENE MOLECULE, Journal of the Chemical Society, Chemical Communications, (7), 1995, pp. 735-736
The synthesis of two new large cryptands 7a and 7b has been carried ou
t and the X-ray structure of 7b confirms that a benzene guest molecule
is encapsulated centrally in its cavity.
