Rhodium-Catalyzed Rearrangement of S/Se-Ylides for the Synthesis of Substituted Vinylogous Carbonates
Reddy, Angula Chandra Shekar,Anbarasan, Pazhamalai
supporting information, p. 9965 - 9969 (2019/12/24)
An efficient rhodium-catalyzed unprecedented oxa-[2,3]-sigmatropic rearrangement of sulfur ylide derived from α-thioesters/ketones and diazo carbonyl compounds has been accomplished for the synthesis of various sulfur-tethered vinylogous carbonates in good to excellent yields. Important features of the developed reaction include wide functional group tolerance, excellent chemo- and regioselectivity, and efficient rearrangement involving the carbonyl motif. The present reaction also equally works well with α-selenoesters for the synthesis of seleno-containing vinylogous carbonates.
Scope and Mechanism of Iridium Porphyrin-Catalyzed S-H Insertion Reactions between Thiols and Diazo Esters
Dairo, Taiwo O.,Woo, L. Keith
, p. 927 - 934 (2017/04/21)
The insertion of carbenes derived from ethyl diazoacetate (EDA), methyl diazoacetate (MDA), methyl phenyldiazoacetate (MPDA), and methyl (p-tolyl)diazoacetate (MTDA) into the S-H bonds of aromatic and aliphatic thiols was catalyzed by (5,10,15,20-tetratolylporphyrinato)methyliridium(III), Ir(TTP)CH3, at ambient temperatures. Yields of the resulting thioether products were as high as 97% for aromatic thiols, with catalyst loadings as low as 0.07 mol %. Thiol binding to Ir(TTP)CH3 was measured at 23 °C by titration studies, providing equilibrium constants, Kb, ranging from 4.25 × 102 to 1.69 × 103 and increasing in the order p-nitrobenzenethiol a mechanism that involves a rate-limiting nucleophilic attack of thiols on an iridium-carbene species, where the major species present in the reaction solution is an inactive, hexacoordinate Ir-thiol complex.
