Antimony pentachloride-benzyltriethyl ammonium chloride complex

Figure 3.1 Antimony pentachloride-benzyltriethyl ammonium chloride complex.

The antimony pentachloride-benzyltriethyl ammonium chloride complex (SbCls-TEBA, Figure 3.1), shows quite interesting catalytic efficiency in the acylation of activated aromatic compounds (i.e., toluene, xylenes, aryl ethers) with aromatic and chloroacetyl chlorides. Reactions are carried out with SbCls-TEBA (5% mol) in boiling nitromethane, giving ketones in 73%-96% yield. The catalyst has many advantages, such as ready access, minimal toxicity, reusability, insensitivity to atmosphere and moisture.
