1,1-Bis(diphenylphosphino)methane (dppm), is an organophosphorus compound with the formula CH 2 (PPh 2) 2. Dppm, a white, crystalline powder, is used in inorganic and organometallic chemistry as a ligand. [1] It is more specifically a chelating ligand because it is a ligand that can bond to metals with two phosphorus donor atoms.

PdCl 2 + 2 PPh 3 → PdCl 2 (PPh 3) 2 PdCl 2 (PPh 3) 2 + 2 PPh 3 + 5 ⁄ 2 N 2 H 4 → Pd(PPh 3) 4 + 1 ⁄ 2 N 2 + 2 N 2 H 5 Cl. Both steps may be carried out in a one-pot reaction, without isolating and purifying the PdCl 2 (PPh 3) 2 intermediate. [5] Reductants other than hydrazine can be employed, including ascorbic acid.

Tetraphenylphosphonium chloride is the chemical compound with the formula [(C 6 H 5) 4 P]Cl, abbreviated Ph 4 PCl or PPh 4 Cl or [PPh 4]Cl, where Ph stands for phenyl. Tetraphenylphosphonium and especially tetraphenylarsonium salts were formerly of interest in gravimetric analysis of perchlorate and related oxyanions.
