Only a few reports have appeared of reactions of substituted 1,8-phenanthrolines. From spectroscopic evidence it has been established that 4-hydroxy-2-trifluoromethyl-l,8-phenanthroline exists as the 4-oxo tautomer.38 It is converted with phosphorus bromides into 4-bromo-2-trifluoromethyl-l,8-phenanthroline. The bromo group has been replaced by lithium with w-butyl lithium and the lithio derivative converted into 4-carboxy-2-trifluoromethyl-l,8-phenanthroline with carbon dioxide.215... [Pg.52]

The method we shall use starts with bromine and allows it to react with red phosphorus and water. Phosphorus and bromine combine very easily to form PBr3, but the phosphorus bromide hydrolyzes completely and hydrogen bromide passes over to the absorption flask. [Pg.144]

Azole approach. Cyclization of the thiazolo oxime (424) with acid catalysis gives the fused pyridazine 7-oxide (425) in which the oxide bond is cleaved in the usual way by the reaction with phosphorus bromide (69JCS(C)227o). Fused 1,2,4-triazines can be constructed from appropriately substituted thiazole-2-hydrazones as shown for (426) (79MI42901). [Pg.695]

To 50 g. of propionic add and 7.6 g. of dry amorphous phosphorus are added, drop by drop, 66 7 g. of bromine, at about which point evolution of hydro-bromic add ceases. Through the intermediate formation of phosphorus bromides the acid is converted into the bromide according to the equation (Zelinsky) ... [Pg.20]
