Chlorination occurs adjacent to the isoprene units to form allylic chlorines .
氯化发生在异戊二烯单元附近形成烯丙基氯。
The catalytic activities and enantioselectivities of their pd-complexes were assessed in asymmetric allylic alkylation .
考察了它们与过渡金属把配合物在不对称烯丙基烷基化反应中的催化活性和不对称诱导作用。
We see the symmetry we have attributed to allylic particles on the basis of the resonace theory ; the two ends of each of these molecules are equivalent .
我们看到了曾经根据共振论而归因于烯丙基型粒子的对称性，所有这些分子中每个分子的两端都是等性的。
However , there have been only limited and aporadic reports dealing with the direct cleavage of the c-o bond in allylic alcohols on interaction with a transition metal complex . Successful applications using allylic alcohols directly in catalytic processes are even more limited .
Because these substrates are synthesized from the corresponding allylic alcohols , palladium-catalyzed conversion of allylic alcohols directly into allylation products are highly desirable , especially from the viewpoint of the atom economy .
