decarboxylations and to determine the scope of this process. The results from this study show that hydrogenatomtransferfrom chloroform occurs directly under kinetic control and is aided by a combination of polareffects and quantum mechanical tunneling. Chloroform acts as an effective hydrogenatom donor for primary, secondary, and tertiary alkyl radicals, although significant chlorination was also observed

Functionalization of C(sp3)–H bonds represents the most straightforward and atom-economical transformation in organic synthesis. An innovative approach integrating photocatalytic hydrogen atom transfer (HAT) and transition metal catalysis has made significant progress in the coupling of α-heterosubstituted C–H bonds with alkyl halides. However, unactivated alkanes were ineffective as a result of the
C(sp 3 )–H 键的官能化代表了有机合成中最直接且最经济的转化。结合光催化氢原子转移(HAT)和过渡金属催化的创新方法在α-杂取代C-H键与卤代烷的偶联方面取得了重大进展。然而,由于大量副产物的形成,未活化的烷烃是无效的。在此,我们证明了环烷烃和苄基溴/伯烷基碘偶联中的直接 HAT 和镍催化作用。此外,十钨酸四丁基铵(TBADT)也被回收和再利用。
On social percolation and small world network

The social percolation model is generalized to include the propagation of two mutually exclusive competing effects on a one-dimensional ring and a two-dimensional square lattice. It is shown that the result depends significantly on which effect propagates first i.e. it is a non-commutative phenomenon. Then the propagation of one effect is studied on a small network. It generalizes the work of Moore and Newman of a disease spread to the case where the susceptibility of the population is random. Three variants of the Domany-Kinzel model are given. One of them (delayed) does not have a chaotic region for some value of the delay weight.
