A tetrabutylammonium bromide catalyzed trifluoromethylation/cyclization reaction of o-aralkynylaryl aldehydes with trimethyl(trifluoromethyl)silane and cesium fluoride has been developed. A variety of 1-alkylidene-3- (trifluoromethyl)phthalans were prepared in moderate to excellent yields by tandem nucleophilic addition and cyclization. Georg Thieme Verlag Stuttgart New York.
