In homogeneous catalysis, the catalyst is in the same phase as the reactant. The number of collisions between reactants and catalyst is at a maximum.In a patent, 497-25-6, name is Oxazolidin-2-one, introducing its new discovery. 497-25-6
(Chemical Equation Presented) Large-scale syntheses of 3-(cycloprop-2-en-1- oyl)oxazolidinones from acetylene and ethyl diazoacetate are described. Unlike other cyclopropenes that bear a single substitutent at C-3, these compounds are stable to long-term storage. Although the cyclopropene derivatives are unusually stable, they are reactive toward cyclic and acyclic dienes in stereoselective Diels-Alder reactions.
I am very proud of our efforts over the past few months and hope to 497-25-6 help many people in the next few years. 497-25-6
