Phenylglyoxylic acid can be employed in a very low catalyst loading (1 mol%) for the introduction of a low‐cost, simple, photochemical protocol for the ATRA reaction of BrCCl3 with olefins.

Pd(OAc)2 combined with phosphines catalyzes homolytic cleavage of the C—Cl bond of CCl4 and CCl3CO2CH3 leading to facile addition to olefins under mild conditions. BrCCl3 also reacts with olefins to give 1,1,1-trichloro-3-bromoalkanes. The reaction is accelerated under CO atmosphere, and the presence of bases such as NaOAc or K2CO3 is essential to attain high yields of the adducts.
Pd(OAc)2与膦结合可催化CCl 4和CCl 3 CO 2 CH 3的C-Cl键的均相裂解,导致在温和条件下易于加成烯烃。BrCCl 3也与烯烃反应生成1,1,1-三氯-3-溴代烷烃。该反应在CO气氛下被加速,并且碱例如NaOAc或K 2 CO 3的存在对于获得高产率的加合物是必不可少的。

Addition reaction of CCl4, CCl3Br, and CCl3CO2Me to olefins proceeded under mild conditions to afford 1 : 1 adduct in high yields by using palladium–phosphine complexes as a catalyst in the presence of bases. The reaction proceeded even at room temperature.
only in the fundamentals but also in the economic and ecological fingerprint of organic reactions. Here we show that few-layer black phosphorous (FL-BP), a recently discovered and now readily available 2D material, catalyzes different radical additions to alkenes with an initial turnover frequency (TOF0) up to two orders of magnitude higher than representative state-of-the-art metal complex catalysts
