Grignard-type additions were readily achieved under the mediation of CuI (10 mol%) and samarium (2 equivalent) by employing various organohalides, e.g. benzyl, aryl, heterocyclic and aliphatic halides (Cl, Br or I), and diverse carbonyl compounds (e.g. carbonic esters, carboxylic esters, acid anhydrides, acyl chlorides, ketones, aldehydes, propylene epoxides and formamides) to afford alcs., ketones and aldehydes, resp., with high efficiency and chemoselectivity, in which the organosamarium intermediate might be involved. This study involved multiple reactions and reactants, such as Diphenyl carbonate (cas: 102-09-0Application In Synthesis of Diphenyl carbonate).
Diphenyl carbonate (cas: 102-09-0) belongs to esters. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Application In Synthesis of Diphenyl carbonate
