Palladium-catalyzed direct carboxylation of aryl bromides with carbon dioxide.
A novel protocol for the direct carbon dioxide insertion (CO(2)) into aryl halides in a catalytic manner is presented herein. Unlike other carboxylation methods using CO(2), there is no need for the synthesis of the corresponding organometallic intermediates. Additionally, and in contrast to the well-established carbonylation processes, our protocol does not use highly toxic CO for the preparat...
متن کاملDirect carboxylation of allylic halides with carbon dioxide in the presence of indium.
A highly regioselective indium-mediated allylation of carbon dioxide starting from simple allylic halides (X = I, Br, Cl) has been developed. No transition metal catalyst is needed and an inert atmosphere is not necessary. The reaction tolerates a wide range of synthetically attractive functional groups with a very high branched regioselectivity.
متن کاملA synthesis of α-amino acids via direct reductive carboxylation of imines with carbon dioxide.
A method for the synthesis of α-amino acids by direct reductive carboxylation of aromatic imines with CO2 is described. The protocol employs readily available commercial reagents and serves as a one-step alternative to the Strecker synthesis.
متن کاملAdamantane-1-ammonium benzoate
In the title molecular salt, C(10)H(15)NH(3) (+)·C(7)H(5)O(2) (-), both carboxyl O atoms act as acceptors for strong N-H⋯O inter-molecular hydrogen-bond inter-actions with the ammonium group in the cation, generating infinite chains along the b axis. A weak C-H⋯π inter-action is also present.
