Alkylplumbonic acids

Meyer reaction. Preparation of alkylstannonic acids byreacting alkali stannite with an alkyl iodide. When applied to alkali arsenites or plumbites, the reaction yields alkylarsonic and alkylplumbonic acids, respectively. 

Little is known about R2Pb(OH)2 compounds. Dehydration is possible to give R2PbO, which could be a polymer, perhaps cyclic. Even less known are the alkylplumbonic acids, RPb(0)0H and their hydrated form RPb(OH)3. The first certainly does not exist as a monomer. 

Because so little is known about the products it only can be assumed that similar relations as for the analogous organotin compounds (189) hold, that is, that the dialkyllead oxides are in fact polyplumboxanes (—R2Pb— O—) , perhaps cyclic with w = 3 or 4. The alkylplumbonic acids could then have similar but cross-linked structures. A number of plumbosiloxanes are known (52,245), as well as other compounds with Pb—O—M groupings (52).
