The research investigates the coordination chemistry of functionalized phosphorane ylids, specifically focusing on the formation of new manganese and rhenium complexes with triphenylphosphonium-alkandithiocarboxylate ligands. The study explores the reactions of phosphorane ylids with heteroallenes, particularly carbon disulfide, to form zwitterionic adducts and subsequent cycloaddition products like 1,2,4-trithiolanes. Key chemicals involved in the research include isopropylidene triphenylphosphorane, carbon disulfide, manganese and rhenium carbonyl halides, and various phosphonium salts. The research also examines the stability and spectral properties (IR, NMR, UV) of the resulting complexes, which are found to be influenced by the substituents and the metal centers. The study provides insights into the coordination behavior of phosphonium-betaines and their potential applications in organometallic chemistry.
