Aluminum complexes phosphorus oxychloride

Aluminum chloride-phosphorus oxychloride complex, 31, 88 Amberlite IR-4B resin, 32, 13 Amidation, of isocyanic acid with bromo-aniline and other aromatic amines, 31,8... [Pg.52]

Chloro-(/7-cyanophenyl)phenylphosphine 349 Dichloro(phenyl)phosphine (60 g) is added to a slurry of i -cyanobenzenediazonium tetrafluoroborate (72 g) and copper(i) bromide (2.4 g) in dry isopropyl acetate (300 ml). After about 20 min a violent reaction sets in which is moderated by external cooling so that the temperature remains between 20° and 40°. When gas evolution ceases, aluminum turnings (8 g) are added and the mixture is stirred for 2 h at 40-50°. Then the liquid is decanted from unused aluminum, and phosphorus oxychloride (51 g) is added to decompose the aluminum chloride complex. Distillation then affords a forerun (5 g), followed by the main fraction (39 g, 47%) between 15870.7 mm and 195°/ 3.1 mm (owing to unavoidable decomposition the pressure does not remain constant during the distillation). Further distillation gives a product boiling at 16270.2 mm. [Pg.737]

Controlled alkylation of phosphorus oxychloride may also be accomplished using a modification of this approach. Reaction of alkyl-aluminum dichloride with phosphorus oxychloride generates the aluminum chloride complex of the alkylphosphonodichlori-date,54 which may be isolated as the simple compound or directly used in reaction to generate other derivatives of the alkylphospho-nic acid. [Pg.120]
