実験手順

The cyclotridecanecarbaldehyde listed above is also a novel compound which is prepared in the following manner: Titanium tetrachloride is added to a mixture of zinc dust, anhydrous tetrahydrofuran and dibromomethane. To the resulting mixture is added cyclotridecanone to yield methylene cyclotridecane which is then epoxidized with m-chloroperbenzoic acid. After purification, the epoxidized product is reacted with boron trifluoride-ether complex in anhydrous dichloromethane to yield cyclotridecanecarbaldehyde.
