, p. 519 - 524 (1992)
The kinetics of the bromination of tetraazaporphin by bromine in glacial acetic acid were studied.It is suggested that bromination takes place through the formation of a molecular complex between porphyrin and bromine.Possible reaction schemes are proposed.

A compound of Formula I M is selected from Pd or Pt; X is selected from N or CR3; each R1 and R2, which can be the same or different, and R3, are independently selected from the group consisting of hydrogen, deuterium, halogen, alkoxide, alkyl, cycloalkyl, heteroalkyl, heterocycle, cycloalkene, aryl, heteroaryl, and combinations thereof; wherein at least one of R1, R2, or R3 is selected from the group consisting of: a partially or fully fluorinated alkyl; a partially or fully fluorinated cycloalkyl; and a group of formula A connected to a carbon of one of Y1 to Y4 formula A, wherein Y1, Y2, Y3, and Y4 are independently selected from C or N, and no more than two of Y1 to Y4 is N; and Z is selected from the group consisting of O, S, NR5, and CR6R7. An OLED that includes an organic layer positioned between two electrodes, the organic layer including a compound of Formula I is also described. A consumer product that includes the OLED, and a formulation that includes a compound of Formula I, is also described.

Bromination of 5,10,15,20-tetraazaporphine with N-bromosuccinimide in glacial acetic acid or chloroform involves formation of molecular complex with bromine and yields a mixture of bromo derivatives. Chromatographic separation of the product mixture on silica gel gave mono-, 2,7-di-, 2,12-di-, 2,7,12-tri-, and 2,7,12,17-tetrabromo-5,10,15,20-tetraazaporphines.
BROMINATION OF TETRAAZAPORPHIN

, p. 690 - 693 (2007/10/02)
The bromination of tetraazaporphin by Br2 in glacial acetic acid takes place through the formation of a molecular complex with bromine. 2,7,12,17-Tetrabromotetraazaporphin was obtained as a result of the reaction and identified, and the optimum conditions for its synthesis were determined.
