Halogen-lithium exchange reaction of -(silyl)bromobenzene with -BuLi afforded -(silyl)lithiobenzene , which was reacted with (alkoxy)diarylboranes to form borate intermediates . Treatment of with chlorotrimethylsilane formed -(alkoxysilyl)(diarylboryl)benzenes . The C-O bond in was activated by intramolecular interaction between the oxygen atom and the boron atom. readily reacted with MeOH and EtOH to afford the corresponding alkoxysilanes and , respectively. Treatment of with 1,4-diazabicyclo[2.2.2]octane (DABCO) afforded the silyloxyborate complex .
