Trifluoromethyl Group 2B compounds: formation of mono- and bis-(trifluoromethyl)–platinum, –palladium, and –nickel trialkylphosphine complexes from the reaction of (CF3)2Cd·glyme [glyme =(CH2OMe)2] with the diligand metal dihalides

Abstract

The reaction of (CF₃)₂Cd·glyme [glyme =(CH₂OMe)₂] with bis(trialkylphosphine) Group 8B dihalides like Br₂Ni(PEt₃)₂ during short periods of time, 0·5–5 h, results in the formation of the monosubstituted compounds (CF₃)BrNi(PEt₃)₂, (CF₃)BrPd(PEt₃)₂, and (CF₃)IPt(PBuⁿ₃)₂ in 60–70% yield; over longer periods of time, in the presence of an excess of (CF₃)₂Cd·glyme, the disubstituted compounds, (CF₃)₂M(PEt₃)₂(M = Ni, Pd, and Pt) are formed.
