ABSTRACT
The B(C6 F5 )2 -substituted borole 2â
SMe2 was obtained from the phenyl bis(trimethylsilylethynyl) borane SMe2 adduct (1â
SMe2 ) by a synthetic sequence containing a rare 1,1-hydroboration reaction. Subsequent thermolysis at 50 °C converted it to the bicyclic borenium/borate zwitterion 3â
SMe2 . Photolysis of 3â
SMe2 gave the diboracyclohexadiene derivative 4â
SMe2 , which after ligand exchange with N,N-dimesitylimidazolylidene and deprotonation gave the 1-bora-3-boratabenzene anion derivative as its potassium salt 6. Some unique follow-up reactions of the unsaturated diboron containing six-membered heterocycles were investigated.
