%X The reaction of [(Cp*Ir)2(米-dmpm)(米-H)][OTf] (2) [Cp* = 灰5-C5Me5, dmpm = bis(dimethylphosphino)methane] with 2,3-dihydrofuran gives [(Cp*IrH)2(米-dmpm){米-(2,3-dihydrofuranyl)}][OTf] (3) in an isolated yield of 70% via the C每H bond activation at the 5-position of 2,3-dihydrofuran. Complex 3 is slowly converted into [(Cp*Ir)2(米-dmpm)(米-C=C(H)CH2CH2OH)][OTf] (4) quantitatively via the proton-mediated C每O bond activation. The reaction of 2 with ethyl vinyl ether gives [(Cp*Ir)2(米-dmpm)(米-CH=CH2)][OTf] (5) in the isolated yield of 64% via the successive activation of C每H and C每O bonds. View Full-Tex
