Di-tert-butyl 2,2'-(biphenyl-2,2'-diyl-dioxy)diacetate.

ABSTRACT: The title compound, C(24)H(30)O(6), does not exhibit ?-? inter-actions due to the steric effect of the bulky tert-butyl groups present in the mol-ecule. The presence of these groups at the 2 and 2' positions hinders the free motion of the benzene rings relative to each other, causing them to adopt an anti-periplanar arrangement. The benzene rings are twisted by just under 50.96?(17)° with respect to each other. The carbonyl groups within the mol-ecule are directed in different directions, one towards the biphenyl group and the other away from it. The mol-ecules are linked together by C=O?H-C hydrogen bonds.

The title compound, C(24)H(30)O(6), does not exhibit π-π inter-actions due to the steric effect of the bulky tert-butyl groups present in the mol-ecule. The presence of these groups at the 2 and 2' positions hinders the free motion of the benzene rings relative to each other, causing them to adopt an anti-periplanar arrangement. The benzene rings are twisted by just under 50.96 (17)° with respect to each other. The carbonyl groups within the mol-ecule are directed in different directions, one to  ...[more]
