WebThe C C bonds in cyclopropyl rings can act as powerful donors and thus greatly stabilize a carbocation with a cyclopropyl ring in α position. To illustrate, consider the relative rates of S N 1solvolysis of the tertiary substrates in Fig. 3.49. 103 Interestingly, replacement of a phenyl group by a cyclopropyl group leads to a large increase in the reaction rate … WebCyclopropyl phenyl ketone was used to prepare α-cyclopropylstyrene by the Wittig reaction in dimethyl sulfoxide. It was used as starting reagent during the (Z)-titanium enolate formation from cyclopropyl ketones via TiCl 4-n-Bu 4 NI-induced ring opening reaction. Packaging. 5, 25, 100 g.
