I found the field of Chemistry very interesting. Saw the article Late-Stage Diversification of Biarylphosphines through Rhodium(I)-Catalyzed C-H Bond Alkenylation with Internal Alkynes published in 2020.0. Safety of 1-Chloro-2-methylbenzene, Reprint Addresses Soule, JF (corresponding author), Univ Rennes, CNRS, ISCR UMR 6226, F-35000 Rennes, France.. The CAS is 95-49-8. Through research, I have a further understanding and discovery of 1-Chloro-2-methylbenzene
We report herein P(III)-directed C-H bond alkenylation of (dialkyl)- and (diaryl)biarylphosphines using internal alkynes. Chloride-free [Rh(OAc)(COD)](2) acts as a better catalyst than commercially available [RhCl(COD)](2). Conditions were developed to control the mono- and difunctionalization depending on the alkyne stoichiometry. One of these novel bisalkenylated (dialkyl)biarylphosphines was employed for the preparation of a palladium(II) complex, and some of these functionalized ligands outperformed their corresponding unfunctionalized phosphines in Pd-catalyzed amidation with sterically hindered aryl chlorides.
