The diversity‐oriented desulfonylative functionalization of alkyl allyl sulfones with various sulfone‐type reagents by radical chemistry has been developed. The readily installed allylsulfonyl moiety acts as a C‐radical precursor, which is substituted by various functionalities using sulfur‐based radical trapping reagents. The generality of this approach is documented by the successful desulfonylative

alkynyl triflone 1b is studied by density functional theory (DFT) calculations for trans-hydroboration. Moreover, a regiodivergent deuterated semihydrogenation of alkynyl triflones has also been developed using D2O as the deuterium source. A variety of diversity-oriented D-containing vinyl triflones were prepared in good to excellent yields with excellent deuterium incorporation ratios. Synthetic manipulations
在这里,我们提出了炔基砜与 NHC-硼烷的直接 α-反式选择性硼氢化反应,无需催化剂。该反应与多种底物兼容,能够以令人满意的产率有效生产结构多样的α-硼基化乙烯基砜。通过密度泛函理论 (DFT) 计算反式硼氢化反应,研究了从 NHC-硼烷2a到炔基三氟酮1b的氢化物转移。此外,还开发了使用D 2 O作为氘源的炔基三氟酮的区域发散氘化半氢化反应。多种面向多样性的含 D 乙烯基三氟乙烯以良好至优异的产率制备,并且具有优异的氘掺入比。实现了氘化产物的合成操作,将其转化为有价值的氘化分子,表明了该方案的实用性。
