《Palladium-Catalyzed ortho-Benzoylation of Sulfonamides through C-H Activation: Expedient Synthesis of Cyclic N-Sulfonyl Ketimines》 was published in Advanced Synthesis & Catalysis in 2020.

The ortho-carbonylation of sulfonylarenes by non-hazardous aryl aldehydes as a carbonyl precursor was reported. In this method, the sulfonamide group served as a directing group for C-H activation in the presence of a Pd catalyst under ligand-free conditions. The scope of this strategy was extended to the one-pot two-step synthesis of cyclic N-sulfonyl ketimines under mild reaction conditions. Our approach could be considered as an alternative by circumventing the use of highly reactive organolithium or Grignard reagents to access a wide range of biol. potent cyclic N-sulfonyl ketimines. In the part of experimental materials, we found many familiar compounds, such as 4-Chlorobenzenesulfonyl chloride(cas: 98-60-2Recommanded Product: 98-60-2)
4-Chlorobenzenesulfonyl chloride(cas: 98-60-2) belongs to organochlorine compounds. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Recommanded Product: 98-60-2
