alkyl transfer

The other is the process in which the monomer containing "reactive group" is grafted at the end of polyolefine molecular chain, acting as a chain transfer agent, such as borane, para-methyl styrene, silane and alkyl zinc etc.

二是含反应性基团的单体接入聚烯烃分子链末端起链转移剂作用，这类链转移剂有硼烷、p-MS、硅烷和烷基锌等。

with different side chains at the 3-position of the phthalide, either hydride transfer or alkyl transfer would take place in the rearrangement reaction depending upon the stability of resulting carbonium species, leading to different products.

研究了3-位不同烷基取代的苯酞类化合物在三氯化铝作用下的重排反应。在重排过程中，既有氢迁移，也会有烷基迁移，这取决于形成的碳正离子的稳定性。

excellent selectivity in alkyl transfer was noted in the sequence of phch 2 > primary alkyl > secondary alkyl.

季铵盐中烷基的转移具有较好的选择性,其优先顺序为:苄基>伯烷基>仲烷基.
