Convenient synthesis of phosphinecarboxamidein by hydrophosphination of isocyanates (and isothiocyanates) was achieved without catalyst and solvent. This system shows shorter reaction time, high yield, and good functional group tolerance.
Here,
a commercially
available easy-to-handle oxovanadium(V) compound
is demonstrated to serve as an efficient catalyst for the synthesis
of ureas from disilylamines and carbon dioxide under ambient pressure.
The catalytic activation of carbon dioxide proceeds without any additives,
demonstrating a broad substrate scope and easy scalability to validate
this catalytic activation of carbon dioxide. This catalytic system
can be applied to the synthesis of unsymmetric ureas and chiral urea
with retention of chirality.
Catalytic activation of carbon dioxide as a C1 building block under ambient pressure was performed by using a commercially available oxovanadium(v) catalyst for the synthesis of ureas.
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.
