Palladium-catalysed dimerisation-distannylation of arynes: synthesis and reaction of 2,2'-distannylbiaryls.
Two molar amounts of arynes were found to insert into a Sn-Sn bond of a distannane in the presence of a sub-stoichiometric amount of a palladium-phosphite complex, affording straightforwardly 2,2'-distannylbiaryls.
