Abstract

Abstract A series of 2, 4, 6-triarylphosphinines were prepared and investigated in the base- assisted cyclometalation reaction using [Cp* IrCl 2] 2 (Cp*= 1, 2, 3, 4, 5- pentamethylcyclopentadienyl) as the metal precursor. Insight in the mechanism of the C [BOND] H bond activation of phosphinines as well as in the regioselectivity of the reaction was obtained by time-dependent 31 P {1 H} NMR spectroscopy. At room temperature, 2, 4, ...
