摘要

We report the first measured activation parameters for the additions of CCl2 and CClF to simple alkenes and demonstrate the existence of enthalpic barriers for CCl2 additions to cyclohexene and 1-hexene. With these two alkenes, additions of PhCCl are “dominated” by entropic contributions to Δ G‡ and additions of CCl2 display comparable contributions of Δ H‡ and Δ S‡, while CClF additions feature dominant enthalpic contributions to Δ G‡. ...
