alkyl–aryl coupling reaction between sulfones and arylboron compounds has remained a challenge. We report the first iron-catalyzed radical difluoroalkylation of arylborates with N-heteroaryl sulfones. The coordination between the iron catalyst and the nitrogen atom of N-heteroaryl sulfones was identified to be important in overcoming the reductionpotentiallimitation of sulfones in the intermolecular single-electron-transfer
Heterocyclic compounds as Wee1 inhibitors are provided. The compounds may find use as therapeutic agents for the treatment of diseases and may find particular use in oncology.

A visible-light-triggered radical cascade sulfonylation/aryl migration/desulfonylation and C–S/Se bond formation reaction of butenyl benzothiazole sulfone with thiosulfonates or selenosulfonates is developed. This study affords the 1,2,4-trifunctionalization of butenyl benzothiazole sulfone derivatives under mild conditions.

carbon tetrachloride, benzene and dioxane has been examined, and the conformation of their dimers discussed. The solvent effect on the electric dipole moments of these compounds has been briefly examined. Dipolemoment analysis of dimethyl sulphoxide and dimethyl sulphone can only provide a rough value for the intrinsic bond moment (i.e. due to the bonding electrons) and bond order (1 + c = 1.4) of oxy-sulphur
摘要 研究了二甲基亚砜和异丙基苯砜在环己烷、四氯化碳、苯和二恶烷中作为溶质的物理状态,并讨论了它们的二聚体构象。已简要研究了溶剂对这些化合物的电偶极矩的影响。二甲基亚砜和二甲基砜的偶极矩分析只能提供氧-硫键的固有键矩(即由于键合电子)和键序(1 + c = 1.4)的粗略值。根据在苯中测量的偶极矩以及异丙基-2-吡啶基砜在溶液中的优选构象,讨论了烷基磺酰基与苯基和 2-吡嗪基的共轭。此外,
