2-trifluoro-1-ethanone with benzylic Grignard reagents affords by 1,2-addition unsaturated allylic alcohols. These alcohols readily undergo dehydration and cyclisation to give trifluoromethylnaphthalenes. The generality of this procedure was established by reaction with diverse benzyl and allyl Grignard reagents and by reaction of a number of unsaturated ketones. The resulting trifluoromethylnaphthalenes were oxidised
1-(3,4-二氢-2-反应ħ -5吡喃基)-2,2,2-三氟-1-乙酮与苄基格氏试剂,得到由1,2-加成不饱和的烯丙醇。这些醇易于脱水和环化,得到三氟甲基萘。通过与各种苄基和烯丙基格利雅试剂反应并通过许多不饱和酮反应来确定该方法的一般性。将所得的三氟甲基萘氧化,得到取代的乙酸和丙酸。
