Reaction with pyrophoric lead

The Hungarian chemist Mezaros1 states that pyrophoric lead can be prepared by reaction of lead oxide with furfural vapors at 290°. It can be purified by washing with benzene and aqueous alcohol. It is described as a new reagent for Wurtz-like reactions, for example ... 

When finely divided, Pb is pyrophoric, but bulk pieces are passivated by coatings of, for example, PbO, and reaction with O2 in air occurs only above a 900 K. Lead reacts very slowly with dilute mineral acids, slowly evolves H2 from hot concentrated HCl, and reacts with concentrated HNO3 to give Pb(N03)2 and oxides of nitrogen. For reactions of Pb with halogens, see Section 13.8. 

LEAD CHROMATE or LEAD(II) CHROMATE (7758-97-6) PbCr04 Noncombustible solid. Violent reaction with sulfur, iron(III) ferrocyanide, azo-dyes. Forms unstable, impact-sensitive and/or pyrophoric mixtures with hydrozoic acid, sodium azide, sulfur, tantalum, trinitrobenzoic acid. Incompatible with azo dyes, ammonia, hydrazine, methyl isocyanoacetate, sodium peroxyborate, urea nitrate. A known human carcinogen. 

OXICLORURO de FOSFORO (10025-87-3) Fumes in moist air. Contact with water, steam, or alcohols produces hydrochloric acid, phosphoric acid, and phosphine gas, which is pyrophoric, with possible ignition or explosion (may be a delayed reaction). Contact with air produces corrosive fumes. Violent reaction with carbon disulfide, 2,6-dimethylpyiidine-M-oxide, dimethyl sulfoxide, ferrocene-l,l -dicarboxylie acid, pyridine, zinc powder. Reacts, possibly -violently, with acids, alkali metals, alkalis, combustible materials, dimethyl formamide, organic matter, zinc powder. Incompatible with acetic anhydride, iV,A -dimethyl formamide, 2,5-dimethylpyrrole, sodium. Rapid corrosion of steel and most metals, except lead, occurs in the presence of moisture.
