This is the first detailed investigation of catalysts suit-
able for lead(IV)-mediated arylations. The results indi-
cate that significant levels of rate acceleration are
possible using diverse ligand donors, and suggest that
further rate enhancement may be possible using suit-
ably designed systems. This is likely to be of consider-
able importance in the design of systems capable of
asymmetric arylations, as well as other novel processes.
Further efforts in this endeavour will be reported in due
course.

19. Formation of p-methoxyphenyllead tricarboxylates: The
carboxylic acid (3 equiv.) and p-methoxyphenyllead tri-
acetate (1 equiv.) were dissolved in toluene. The mix-
ture was stirred for 20 min, then the solvent was
removed in vacuo at 40°C using a rotary evaporator.
The resulting solid was then redissolved in toluene,
stirred for a further 20 min and the solvent was again
removed in vacuo. This was repeated until no acetic
acid or acetate could be detected by 1H NMR spec-
troscopy (usually three cycles).
