(11) Reactions of phenylboronate ester 1 with p-bromotoluene and
3-iodopyridine gave <5% and 20% yields of the corresponding coupled
products, respectively. Reactions of 4-methoxyphenylboronate ester
with 4-iodonitrobenzene and 2-iodobenzotrifluoride afforded less than
20% coupled product.

Reaction of 43 with p-iodotoluene using TEMPO and galvinoxyl as
free radical scavengers afforded the coupled product in <10% yield,
indicating that the reaction could involve aryl free radicals.
