Selective alkyl ether cleavage by cationic bis(phosphine)iridium complexes
Jones, Caleb A. H.,Schley, Nathan D.
supporting information, p. 1744 - 1748 (2019/02/20)
Catalysts capable of heterolytic silane activation have been successfully applied to the conversion of alkyl ethers to silyl ethers via C-O bond cleavage. The previously-reported cationic pincer-supported iridium complex for this transformation suffers fr
Oxidative asymmetric umpolung alkylation of Evans' β-ketoimides using dialkylzinc nucleophiles
Targel, Tom A.,Kumar, Jayprakash N.,Shneider, O. Svetlana,Bar, Sukanta,Fridman, Natalia,Maximenko, Shimon,Szpilman, Alex M.

Umpolung alkylation of Evans' auxiliary substituted β-ketoimides affords the diastereomerically pure products in yields ranging from 40 to 80%. The reaction itself proceeds with diastereoselectivities between 3:1 and 18:1. Dialkylzinc serves as the nucleo
Chlorination of aliphatic primary alcohols via triphosgene-triethylamine activation
Ayala, Caitlan E.,Villalpando, Andres,Nguyen, Alex L.,McCandless, Gregory T.,Kartika, Rendy
supporting information; experimental part, p. 3676 - 3679 (2012/09/08)
Activation of primary aliphatic alcohols with triphosgene and triethylamine mixtures afforded either alkyl chloride or diethylcarbamate products, and the switch in selectivity appeared to be driven by sterics. The reaction conditions to achieve this highly useful transformation were unexceptionally mild and readily tolerated by a wide range of sensitive functionalities.
