I found the field of Chemistry very interesting. Saw the article delta-Cyano substituted para-quinone methides enable access to unsymmetric tri- and tetraarylmethanes containing all-carbon quaternary stereocenters published in 2020. HPLC of Formula: C8H10O2, Reprint Addresses Li, W (corresponding author), Shandong Univ Tradit Chinese Med, Sch Pharm, Dept Pharmaceut Anal, Jinan 250355, Peoples R China.; Sun, ST; Liu, L (corresponding author), Shandong Univ, Sch Chem & Chem Engn, Jinan 250100, Peoples R China.. The CAS is 151-10-0. Through research, I have a further understanding and discovery of 1,3-Dimethoxybenzene
para-Quinone methides bearing an electron-withdrawing cyano group at the exocyclic methylene delta-position were identified as valuable 1,6-conjugate addition building blocks for acyclic all-carbon quaternary stereocenter construction. A wide variety of electron-rich arenes as nucleophiles were tolerated, effectively furnishing diverse unsymmetrical triarylmethanes bearing all-carbon quaternary stereocenters. The robust transformable abilities of the cyano group provide a platform to access other valuable functional group-containing unsymmetrical tri- and tetraarylmethanes that are otherwise difficult to be prepared. Computational studies supported the hypothesis that the cyano group at the delta-position tunes the molecular electron-density distribution, and the stability of para-quinone methides is enhanced by lowering their polymerizability.
