Dioxygen Complexes from the Reactions of [Cp*RuH2(PP)]+ (PP = dppm, dppe) with Air
摘要:
Exposure of [Cp*RuH2(dppm)]BF4 in acetone or methanol to air produced a mixture of [Cp*Ru(O-2)(dppm)]BF4 and [Cp*Ru(O-2)(Ph2PCH2P(O)Ph-2)]BF4. Reaction of Cp*RuCl(dppm) with NaBPh4 in methanol in air produced the dioxygen complex [Cp*Ru(O-2)(dppm)]BPh4, which has been characterized by X-ray diffraction. Reaction of Cp*RuCl(dppm) with H2O2 in the presence of NaBPh4 in air produced [Cp*Ru(O-2)(Ph2PCH2P(O)Ph-2)]BPh4 and PH2P(O)CH2P(O)PPh2. Reaction of [Cp*RuH2(dppe)]BF4 in acetone or methanol with air also produced a mixture of [Cp*Ru(O-2)(dppe)]BF4 and [Cp*Ru(O-2)(Ph2PCH2CH2P(O)Ph-2)]BF4.
