Abstract: A variety of primary vinyl triflates, 7-13, containing a hydrogen, dialkyl groups, arylalkyl, or diary1 groups in the/3 position was prepared from the corresponding aldehydes oia their silyl enol ethers. Treatment of the dialkyl triflates with t-BuOK in a variety of olefins at- 20 to+ 25” afforded methylenecyclopropanes in good yields together with differing amounts of tert-butyl vinyl ethers. Whereas similar treatment of/3-aryl and &hydrogen triflates gave ...
