Trifluoro(2,4,6-tri-t-butylphenyl)silane (ArSiF3, 2), the first silicon compound containing the very bulky 2,4,6-tri-t-butylphenyl group, has been prepared by treatment of ArLi with silicon tetrafluoride.Reaction of 2 with several organolithium compounds gives the corresponding diorganyl derivatives Ar(R)SiF2, R = Me, t-Bu, and Ar, respectively.The fluorosilanes are easily converted into the air-stable hydrosilanes ArSiH3 and Ar(R)SiH2.
