Two new single and double P-pivot lariat ethers have been synthesized and the stability constants of their complexes with silver(i) ions were determined in acetonitrile and methanol solutions.
The identification of complexes containing PNP-lariat ether with Ag(i), Ca(ii), Cu(ii), Cd(ii) and Pb(ii) by ESI-MS technique is presented. The tandem mass spectra of these complexes were done in order to evaluate the stability of the different types of the complexes formed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
