Cycloheptenyl methyl ketone

Cycloalkenes can also be acylated with aluminum chloride or tin tetrachloride as catalyst 627,628 cycloheptene, acetyl chloride, and aluminum chloride give 70% of 1-cycloheptenyl methyl ketone.629 The yield from cyclohexene and phenylacetyl chloride is, however, below 30% but better yields are obtained with acetyl chloride and zinc chloride (60% of 1-cyclohexenyl methyl ketone630,631) or acetic anhydride and tin tetrachloride.632... 

Acetyl chloride added with shaking to a suspension of AICI3 in methylene chloride, excess AICI3 removed, then cycloheptene in methylene chloride added dropwise with stirring at —10°, and the product isolated after additional 5 min. cycloheptenyl methyl ketone. Y 70%. F. e. s. N. Jones, H.T. Taylor, and E. Rudd, Soc. 1961, 1342 method s. Soc. 1959, 4017.
