The palladium-catalyzed carbon-carbon bond formation of organolead(IV) triacetates with terminalalkynes was accomplished with Pd2(dba)3·CHCl3 (5 mol%) and CuI (10 mol%) in the presence of NaOMe (2 equiv.) in MeOH/CH3CN (1:1) at room temperature.

Organolead acetates can be carbonylated in the presence of Pd2(dba)3·CHCl3 (5 mol%) and NaOMe (5 equiv.) in CH3CN under atmospheric pressure of carbon monoxide at room temperature to afford symmetrical ketones.

An efficient synthesis of the moisture-sensitive compound, 4-ethoxycarbonyl-2-methyloxazol-5-one, has been achieved. This compound undergoes high-yielding arylation and vinylation at the 4-position with organolead triacetates to give compounds which in water are converted to α-aryl and α-vinyl N-acetylglycine ethyl esters. These α-substituted glycine derivatives may be kinetically resolved in very

chloroform solution fo a dialk-1-enylmercury or an alk-1-enyltributylstannane results in rapid formation of a relatively unstable species, believed to be an alk-1-enyl-lead triacetat, which can be used for the α-alkenylation of β-dicarbonylcompounds.
