  The regioselectivity of the cobalt-mediated cocyclization of an alkene, an alkyne, and carbon monoxide has been shown to be directed by the use of a soft atom, either sulfur or nitrogen, tethered to the alkene partner by a carbon chain. Direction from the homoallylic position is more efficient thant from the allylic or bishomoallylic position. A rationale is proposed to explain this observation. Studies

  钴介导的烯烃、炔烃和一氧化碳共环化的区域选择性已被证明是通过使用一个软原子（硫或氮）来指导的，硫或氮通过碳链连接到烯烃伙伴上。来自同位烯丙基位置的方向比来自烯丙基或双烯丙基位置的方向更有效。提出了一个基本原理来解释这一观察结果。研究了不同烷基对硫和氮的影响以及其他修饰
