ABSTRACT:

Unsymmetrically substituted 6,13-dihalo-(1,4)-benzoxazino (2,3 b)-phenoxazines (V) have been synthesised by cyclisation of corresponding 2,5-diarylamino 3,6-dihalo-1,4-benzoquinoes (IV). Compounds (IV) were prepared by condensation of arylamine (1) with chloranil/bromanil (II) in the molar ratio of 1:1 and by further condensation of (III) with different arylamines.

KEYWORDS:

6,13-dihalo-(1,4)-benzoxazino (2,3 b)-phenoxazines (V); 2;5-diarylamino; 3; 6-dihalo-1; 4-benzoquinoes (IV)
