摘要
The reaction of 2-(1-alkenyl)-1,3-dithianes with the titanocene-olefin complexes, prepared by the reaction of titanocene dichloride with 2 equiv of alkyllithiums, in the presence of triphenyl-phosphine gave 1-alkenylcyclopropanes in good yields. The similar reaction of substituted 1,3-bis(phenylthio)-1-propenes also proceeded to produce the cyclopropanes.
