light-promoted ring-opening functionalization of unstrained cycloalkanols. Upon scission of an inert cyclic C–C σ-bond, a set of medium- and large-sized rings are readily brominated under mild reaction conditions to afford the corresponding distal bromo-substituted alkyl ketones that are hard to synthesize otherwise. The products are versatile building blocks, which are easily converted to other valuable
本文描述了新颖的,有用的,可见光促进的未应变环烷醇的开环官能化。断开惰性环状C-Cσ键后,一组中等大小和较大的环在温和的反应条件下很容易被
