2,4,6-Triiodobenzoic acid

Triiodobenzoic acid [2338-20-7] M 499.8, m 289-290°. Crystd from aqueous EtOH. [Pg.349]

This reagent is used here for the diazotisation of 4-amino-3,5-diiodobenzoic acid in the preparation of 3,4,5-triiodobenzoic acid (cognate preparation in Expt 6.70). It is also used for the bis-diazotisation of m-phenylenediamine (the... [Pg.921]

Triiodobenzoic acid. Dissolve 6.8g (0.0175 mol) of 4-amino-3,5-diiodobenzoic acid (Expt 6.60) in 30 ml of cold concentrated sulphuric acid, add a large excess (3.0 g, 0.0435 mol) of powdered sodium nitrite and allow the mixture to stand at 0°C for 2 hours. Treat the cold diazonium solution with a solution of 17.0g (0.12 mol) of potassium iodide in 40 ml of water a dark red precipitate separates. Warm the mixture on a water bath until evolution of nitrogen ceases, and remove any residual iodine with a little sodium metabisulphite. Filter the yellow precipitate of crude 3,4,5-trii-odobenzoic acid, and recrystallise from dilute ethanol. The yield of pure acid, m.p. 289-290 °C, is 6.8 g (78%). [Pg.931]

Three alkynyl groups are introduced by the palladium-catalysed reaction of 3,4,5-triiodobenzoic acid with phenylacetylene (equation 9) 3,4,5-triiodonitrobenzene reacts analogously. The hexaethynylation of hexabromobenzene with (trimethylsilyl)acetylene, followed by desilylation, to give 65 has been reported and the syntheses of the hexakis-(butadiynyl)benzenes) 66 (R = t-Bu or SiPr3) have been achieved. ... [Pg.294]

There is little published information of interest to carbohydrate chemists concerning the benzoic acid herbicides. The predominant member, 2,3,6-trichlorobenzoic acid, inhibited uptake and utilization109 of acetate-14C. It shows some auxin-like properties, whereas 2,3,5-triiodobenzoic acid appears to block the transport of natural and synthetic auxins, and has often been termed an antiauxin. The triiodo compound inhibited oxygen (86% at... [Pg.407]
