Ny. Nelson et al., NOVEL PRODUCTS FROM BROMINATION REACTIONS OF 5,10,15,20-TETRAISOPROPYLPORPHYRINS, Chemical communications, (16), 1998, pp. 1687-1688
Bromination reactions of nickel(II) or copper(II) complexes of 5,10,15
,20-tetraisopropylporphyrin afford the unusual porphodimethenes 2-5; c
rystallographic data for some of these compounds are presented and pos
sible mechanisms for their formation are discussed.
