Chemistry is the experimental science by definition. We want to make observations to prove hypothesis. For this purpose, we perform experiments in the lab. , Application In Synthesis of Cyclohexyldiphenylphosphine, 6372-42-5, Name is Cyclohexyldiphenylphosphine, molecular formula is C18H21P, belongs to chiral-phosphine-ligands compound. In a document, author is Wang, Dong, introduce the new discover.
Phosphine-Catalyzed (3+2) Annulation of delta-Acetoxy Allenoates with 2-Sulfonamidomalonate: Synthesis of Highly Substituted 3-Pyrrolines and Mechanistic Insight
A mild and efficient synthetic protocol for 3-pyrrolines via the phosphine-catalyzed (3 + 2) annulation of (delta-acetoxy allenoates with 2-sulfonamidomalonate is reported. The asymmetric version (up to 83% ee) is also achieved by using phosphine (R)-SITCP as the catalyst. Mechanistic experiments disclose that the involved deprotonation of amide N-H and aza-addition to vinyl phosphonium might proceed in a concerted manner.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 6372-42-5. Application In Synthesis of Cyclohexyldiphenylphosphine.
