• Uses: Lead (II) chloride is also known as lead chloride, lead dichloride, and plumbous chloride. Lead chloride is one of the most important lead-based reagents. It occurs naturally in the form of the mineral cotunnite. The solubility of lead chloride in water is low. Lead (II) chloride is the main precursor for organometallic derivatives of lead. Lead chloride has extensive applications in industries. Lead chloride is an intermediate in refining bismuth (Bi) ore. The ore containing Bi, Pb, and Zn is first treated with molten caustic soda to remove traces of acidic elements such as arsenic and tellurium. The molten lead chloride is used in the synthesis of lead titanate (PbTiO3) and barium PbTiO3. It is used in organometallic synthesis to make metallocenes, known as plumbocenes. Lead chloride is used in production of infrared transmitting glass and in production of ornamental glass called aurene glass. This stained glass has an iridescent surface formed by spraying with lead chloride and reheating under controlled conditions. Stannous chloride (SnCl2) is used for the same purpose. Lead (II) chloride (PbCl2) is commonly known as the mineral cotunnite. Lead(II) chloride is used in the synthesis of lead titanate and barium lead titanate ceramics; employed in the production of infrared transmitting glass and ornamental glass (aurene glass); useful as an electrode in geophysical applications and in solar cells. Analytical reagent, preparation of lead salts, as solder and flux. Pattinson's white lead, pigment in white paint, is the basic lead chloride. ▼▲ Industry Application Role/benefit Chemical manufacture Manufacture of other lead compounds Source of lead Glass Infrared transmitting glass Additive Ornamental glass Sprayed to make the glass have an iridescent surface Ceramics Barium lead titanate ceramics Raw material Paint White pigment Ingredient/has natural white color Pigment Pattison's white lead, verona yellow, turner's patent yellow and lead oxychloride Raw material Others Welding Fluxing agent Wire coatings Flame retardant Magnesium-lead dichloride seawater batteries Cathode material Asbestos clutch or brake linings Additive Lead dichloride occurs in nature as the mineral cotunnite. The compound is used in making many basic chlorides, such as Pattison’s lead white, Turner’s Patent Yellow, and Verona Yellow, used as pigments. Also, it is used as a flux for galvanizing steel; as a flame retardant in nylon wire coatings; as a cathode for seawater batteries; to remove H2S and ozone from effluent gases; as a sterilization indicator; as a polymerization catalyst for alphaolefins; and as a co-catalyst in manufacturing acrylonitrile.

Syntheses and molecular structures of some saturated N-heterocyclic plumbylenes

10.1039/b808717b

The research investigates the synthesis and molecular structures of three N-heterocyclic plumbylenes derived from saturated heterocycles. The purpose of the study is to explore the synthesis and structural properties of these compounds, which are analogues of N-heterocyclic carbenes using the heavier group 14 element lead. The key chemicals used in the research include diamines such as 1,2-bis(diisopropylphenylamino)ethane and 1,3-bis(diisopropylphenylamino)propane, as well as lead compounds like PbCl? and bis[bis(trimethylsilyl)amido]lead(II). The researchers synthesized the plumbylenes through deprotonation of diamines followed by reaction with PbCl? or via transamination with bis[bis(trimethylsilyl)amido]lead(II). Single crystal X-ray studies revealed that the compounds exhibit a fine balance between monomer and dimer formation, influenced by the bulk of the organic groups attached to the nitrogen atoms. The study concludes that the plumbylenes possess extremely short and symmetrical Pb–N bonds when only weak intermolecular interactions exist, but for the compound with less sterically demanding substituents, strong intermolecular Pb–N interactions lead to longer and unsymmetrical intramolecular Pb–N separations and pyramidalization of the nitrogen atoms. The findings extend the understanding of the structural properties of N-heterocyclic plumbylenes and their potential applications in coordination chemistry.
