6 ημέρες πριν · The discovery of palladium and its early uses. Palladium is one of the rarest and most valuable metals on the planet – it’s 30 times more scarce than gold. The history of this metal begins in 1802, when English chemist William Hyde Wollaston discovered a new substance while dissolving platinum in a mixture of nitric and hydrochloric acids.
Palladium (0) Palladium forms a range of zerovalent complexes with the formula PdL 4, PdL 3 and PdL 2. For example, reduction of a mixture of PdCl 2 (PPh 3) 2 and PPh 3 gives tetrakis (triphenylphosphine)palladium (0): [19] 2 PdCl 2 (PPh 3) 2 + 4 PPh 3 + 5 N 2 H 4 → 2 Pd (PPh 3) 4 + N 2 + 4 N 2 H 5+ Cl −.
