Abstract:
13,17,73,77-Tetraphenyl-3,5,9,11-tetraoxa-1,7(1,5)-di(1,5-diaza-3,7-diphosphacyclooctana)-2,6,8,12(1,4),4,10(1,3)-hexabenzenacyclododecaphane was obtained by the condensation of bis(hydroxymethyl)phenylphosphine with 1,3-bis(4-aminophenoxy)benzene
and structurally characterised by X-ray single-crystal diffraction.
