《Supported Palladium-Gold Catalyzed Carbonylative Methylthioesterification of Aryl Iodides using Oxalic acid and DMSO as CO and CH3SH Surrogates》 was written by Sharma, Ajay Kumar; Ram, Shankar; Sheetal; Mehara, Pushkar; Chauhan, Arvind Singh; Das, Pralay. Recommanded Product: 1-Iodo-2-methoxybenzene And the article was included in Asian Journal of Organic Chemistry in 2020. The article conveys some information:
The polystyrene supported palladium-gold (Pd-Au@PS) catalyst was prepared and well characterized by HR-TEM, EDX, Elemental Mapping, XPS and P-XRD anal. The Pd-Au@PS NPs displayed the superior catalytic activity than their monometallic forms. First time, the catalyst was applied for methylthioesterification reaction of aryl iodides RI (R = Ph, 4-methylphenyl, naphthalen-1-yl, thiophen-2-yl, etc.) with oxalic acid and DMSO as in situ carbon monoxide (CO) and Me mercaptan (CH3SH) precursor. Yet, there is no report available where DMSO has been applied as CH3SH source for methylthioester RC(O)SCH3 synthesis. The CH3SH and CO are likely to poison the metal catalyst, whereas in Pd-Au@PS catalyst, the beneficial inter-electronic interaction between Pd and Au metals makes the catalyst highly reactive, poisoning resistant and recyclable during the transformation. Moreover, the developed protocol exhibits excellent functional group tolerance for various aryl iodides to deliver the desired products in moderate to very good yields. The experimental part of the paper was very detailed, including the reaction process of 1-Iodo-2-methoxybenzene(cas: 529-28-2Recommanded Product: 1-Iodo-2-methoxybenzene)
1-Iodo-2-methoxybenzene(cas: 529-28-2) participates in palladium catalyzed enantioselective Heck arylation of 2,3-dihydrofuran in the presence of chiral ionic liquids containing L-prolinate and L-lactate anions and non-chiral quaternary ammonium cations.Recommanded Product: 1-Iodo-2-methoxybenzene
