CsF als Fluoridierungsmittel für Organometall-Verbindungen der Elemente der Gruppe 13

CsF as Fluoridation Agent for Organometal Compounds of the Elements of Group 13 Csi-Bu₃AlF] ( 1 ) can be obtained by the reaction of Al(i-Bu)₃ with CsF in toluene. In a halide exchange reaction of Mes*GaCl₂ with CsF in acetonitrile not the desired product Mes*GaF₂ (Mes* = 2,4,6-(t-Bu)₃C₆H₂) was isolated but the metalate CsMes*GaF₃] ( 2 ), formed by the addition of a third unit CsF. A ligand distribution was observed by the treatment of (PhCH₂)₂GaTe(t-Bu)]₂ with CsF in THF. The triorganofluoro gallate Cs{(PhCH₂)₃GaF}]₂ ( 3 ) was isolated. The triorganofluoro gallate CsMe₃GaF] does not react with dry O₂ in THF. With S₈ in THF a reaction was achieved and the diorganodifluoro gallate Cs(THF)_0,5(Me₂GaF₂)] ( 4 ) could be characterized. The treatment of MesInBr₂ with CsF in acetonitrile gives as only identified compound the indate CsMesInBr₃] ( 5 ).
