Generation of Carbamoyl- and Thiocarbamoyllithium Synthons Having a Hydrogen(s) or an Aryl Group on the Nitrogen and Their Trapping with Carbonyl Electrophiles
Dimetalated amides 1 (Y = O) were generated as the synthons of carbamoyllithiums 2 (Y = O) by the reaction of isocyanates with iBu2AlTenBu and a subsequent tellurium-lithium exchange reaction. A series of amide derivatives 3 (Y = O) were obtained by the trapping of dianion 1 with electrophiles. This transformation can be successfully applied to the generation and trapping of thiocarbamoyllithium synthons 1 (Y = S) as well as to the nucleophilic introduction of the parent carbamoyl moiety H2NC(O).

activity of ruthenium(II) complexes, denoted as Ru1–8, which exhibit coordination with nitrogen (amine and amide), oxygen, and sulfur donor atoms, coupled with aryl and aliphatic wingtips. Specifically, the complexes were evaluated for their impact on the MCF-7 breast cancer cell line. A systematic exploration of various parameters, including solubility, donor atom type, metal number, carbon chain length
