Halides, cyclopropylcarbinyl

Cyclopropylcarbinyl halides react with piperidine to give products as shown in equation 8.95. Both products are formed by second-order processes. The distribution of the two products varies with the nature of the R group the larger the R group, the greater is the yield of rearranged product. [Pg.545]

Details of a further variant of the Julia method for conversion of cyclopropyl-carbinols to homoallylic halides have appearedthe carbinols are treated directly with magnesium (or beryllium) halides [equation (20)], thus avoiding the use of strong mineral acids and the need to prepare cyclopropylcarbinyl halides. This procedure is closely related to another reported last year (4,159). [Pg.173]

This method is recommended for conversion of cyclopropylcarbinyl alcohols into the corresponding halides without formation of homoallylic halides via ring cleavage.-Example ... [Pg.554]
