The research focuses on the synthesis and reactions of highly reactive compounds, specifically P-halogenated phosphoranes and ylides. The study explores the reaction of phosphines, such as t-Bu2P(Hlg)=CHR (where R=H or alkoxy), with carbon tetrachloride (CCl4) and carbon tetrabromide (CBr4) to form ylides with a halogen atom at the phosphorus center. These ylides further react with carbon dioxide (CO2) and phenyl isocyanate (PhN=C=O) to produce ketenes and ketenimines, respectively. The research highlights the formation of various compounds, including bromomethylidene-di(tert-butyl)phosphorane and chloromethylidene-di(tert-butyl)phosphorane, and their subsequent reactions to form stable derivatives. The study provides detailed information on the synthesis, stability, and reactivity of these compounds, offering a new method for obtaining phosphorus-containing ketenes and ketenimines.
