Abstract:
The invention relates to perfluoroalkyl group-containing bismuth compounds as Lewis acid catalysts, to specific compounds, and to the method for the production thereof.

Claim (Index 8):
A process for preparing the compound of  claim 5 , comprising reacting a compound of formula (II)\n (C m F 2m+1 ) n Li\u2003\u2003(II), wherein m in each case, independently of one another, denotes 2, 3 or 4, with dichloroarylbismuthane or chloro(diaryl)bismuthane, wherein aryl in the corresponding bismuthane denotes an aryl group having 6 to 10 C atoms, which may be substituted or unsubstituted, and the resultant intermediates of the formula (IIIa) or (IIIb)\n ArBi(C m F 2m+1 ) 2 \u2003\u2003(IIIa) or \n Ar 2 Bi(C m F 2m+1 )\u2003\u2003(IIIb), \n are subsequently reacted with hydrogen chloride, hydrogen bromide, anhydrous HF or CF 3 SO 3 H to give a compound of formula (I), wherein Ar in each case, independently of one another, denotes an aryl group having 6 to 10 C atoms, which may be substituted or unsubstituted, and where the conditions of the reaction with the compound of the formula (II) are that both the water content and the oxygen content are a maximum of 100 ppm.
