THPC can be synthesized with high yield by treating phosphine with formaldehyde in the presence of hydrochloric acid. [1]PH 3 + 4 H 2 C=O + HCl → [P(CH 2 OH) 4]Cl. The cation P(CH 2 OH) 4 + features four-coordinate phosphorus, as is typical for phosphonium salts.
Bis(trimethylsilyl)amine (also known as hexamethyldisilazane and HMDS) is an organosilicon compound with the molecular formula [(CH 3) 3 Si] 2 NH. The molecule is a derivative of ammonia with trimethylsilyl groups in place of two hydrogen atoms.

KOCN is prepared by heating urea with potassium carbonate at 400 °C: . 2 OC(NH 2) 2 + K 2 CO 3 → 2 KOCN + (NH 4) 2 CO 3. The reaction produces a liquid. Intermediates and impurities include biuret, cyanuric acid, and potassium allophanate (KO 2 CNHC(O)NH 2), as well as unreacted starting urea, but these species are unstable at 400 °C.
