Allenyl organometallics

However, reaction of the same allenyl organometallic species with cyclohexenone generates only the four-membered ring cycloadduct (42) (equation 34). In Ae latter case it is likely that the (7i -alle-... [Pg.279]

The mechanism of the condensation between allenyl organometallics and carbonyl groups is thought to be a cyclic Se< (or 5e2 ) process. In the reaction of aldehydes with 1,2-butadienylmagnesium halides, the anti syn product ratio depends on the size of substitutent group of the aldehyde and may be rationalized as shown in (1). ... [Pg.91]
