Synthesis of Aryl Stannanes from Silyl Triflates via Aryne Intermediates.

Aryl stannanes are easily accessible from <italic>o</italic>-silylated aryl triflates in the presence of KF and Bu3SnH. The corresponding arynes are formed in situ, and undergo clean hydrostannation to give a mixture of the regioisomeric aryl stannanes. The whole reaction sequence can also be carried out as a one-pot reaction under microwave irradiation. [ABSTRACT FROM AUTHOR]
