Spherands with functional groups in the outer sphere: synthesis from modified 1,1′:3′,I″-terphenyls
Abstract
Two spherands (1a,c), functionalized in the outer sphere, have been synthesized by oxidative coupling of the dianions of terphenyls; these terphenyls are obtained by aldol condensation of 1,3-diarylpropanones with nitromalonaldehyde.
