Syntheses of 6-Amino-1,3-benzodioxin and Its p-Arylazo-Substituted Calixarenes

Article abstract of DOI:10.1021/jo00083a015

The p-arylazo-substituted calix<4>arenes were synthesized by a diazo-coupling reaction between calix<4>arene and the diazonium salt of 6-amino-1,3-benzodioxin.The monoarylazo-, 1,2-diarylazo-, 1,3-diarylazo-, triarylazo-, and tetraarylazo-para-substituted calix<4>arenes were isolated and characterized by spectral methods. 6-Amino-1,3-benzodioxin was prepared by palladium metal reduction of 6-nitro-1,3-benzodioxin.
