Aniline → Tetrakis(anilinomethyl)phosphanium chloride

Participants

Reaction Steps

Aniline (9.30 g) was added all at once to a slurry of 4.76 g of tetrakis(hydroxymethyl)phosphonium chloride (THPC) in 50 ml of acetone. The THPC dissolved within 1 minute, with slight warming, giving a clear solution that deposited solids on standing. After 2 hr, the mixture was filtered, giving 8.15 g (66.0 percent yield) of tetrakis(anilinomethyl)phosphonium chloride, m.p. 120°-121°. The filtrate, concentrated on a rotary evaporator, left 16.45 g of a neutral, dark yellow liquid. Beilstein tests on these products were strongly positive on the solid fraction and faintly positive on the liquid fraction, showing that most of the chlorine went into the solid fraction.
