Water-initiated hydrocarboxylation of terminal alkynes with CO2and hydrosilane

This work discloses a Cu(ii)-Ni(ii) catalyzed tandem hydrocarboxylation of alkynes with polysilylformate formed from CO2and polymethylhydrosiloxane that affords α,β-unsaturated carboxylic acids with up to 93% yield. Mechanistic studies indicate that polysilylformate functions as a source of CO and polysilanol. Besides, a catalytic amount of water is found to be critical to the reaction, which hydrolyzes polysilylformate to formic acid that induces the formation of Ni-H active species, thereby initiating the catalytic cycle.

Solvent and ligand partition reaction pathways in nickel-mediated carboxylation of methylenecyclopropanes

Methylenecyclopropanes are carboxylated with gaseous carbon dioxide in the presence of a stoichiometric amount of a nickel complex; the reaction pathways are significantly influenced by the reaction solvent and the amine ligand. The Royal Society of Chemi

Iodo-aryl carbonates for use in methods in radiography

A method for using iodo-aryl carbonates, such as for example, p-iodo-benzyl carbonates, p-iodo-sec-phenethyl carbonates, p-iodo-phenethyl carbonates, p-iodo-phenyl carbonates, 3-(p-iodophenyl)propyl carbonates, 3-(p-iodophenyl)butyl carbonates, 2-(p-iodobenzyl)butyl carbonates and 2-(p-iodobenzyl)-n-hexyl carbonates, to provide radiopaques for various radiography purposes in connection with such techniques as X-ray applications including myelography, salpingography, lymphography and bronchography. The method first comprises selecting a compound generally categorized as a carbonate and having the general formula STR1 wherein R represents an alkyl group having from 1 to 10 carbon atoms and R' represents an iodinated phenyl linked directly to the ester oxygen or through an alkyl chain consisting of 1 to 3 carbon atoms. An effective amount of a pharmaceutically acceptable carbonate, as defined herein, is then placed into the subject body cavity and the particular X-ray or other study performed of this area.
