Palladium complex catalyzed Si-Si bond metathesis dimerization of 3,4-benzo-1,2-dimethyl-1,2-diethyl-1,2-disilacyclobut-3-ene and isomerization of the resulting and relevant dimers

Palladium-phosphine complex catalyzed Si-Si bond metathesis dimerization of 3,4-benzo-1,2-dimethyl-1,2-diethyl-1,2-disilacyclobut-3-ene (1b) took place at 80°C to give 3,4,7,8-dibenzo-1,2,5,6-tetramethyl-1,2,5,6-tetraethyl-1,2,5,6-tetrasilacycloocta-3,7-d

Synthesis of a new hypervalent iodine compound, [2-(hydroxydimethylsilyl)phenyl](phenyl)iodonium triflate as a convenient approach to benzyne

A new benzyne precursor, [2-(hydroxydimethylsilyl)phenyl](phenyl)iodonium triflate, is prepared from 1,2-dibromobenzene in good yield. This procedure avoids the use of carcinogenic HMPA and the severe reaction conditions. The reaction of the benzyne precursor with Bu4NF in the presence of a trapping agent under very mild conditions efficiently generates benzyne and gives the benzyne adduct in high yield.
