Extracurricular laboratory:new discovery of 1,5-Diphenylpenta-1,4-dien-3-one

However, they have proven to be challenging because of the mutual inactivation of both catalysts. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 538-58-9

This type of reactivity has quickly become one of the cornerstones of modern catalysis .In a patent, COA of Formula: C17H14O, name is 1,5-Diphenylpenta-1,4-dien-3-one, belongs to chiral-oxygen-ligands compound, introducing its new discovery. COA of Formula: C17H14O

(Chemical Equation Presented) The carbodiimides 5, obtained from reactions of iminophosphorane 4 with aromatic isocyanates, reacted with amines, phenols or ROH to give 2-substituted 5,6,7,8-tetrahydropyrido[4?,3?:4,5] thieno[2,3-d]-pyrimidin-4(3H)-one 7 in the presence of catalytic amount of sodium alkoxide or solid potassium carbonate in satisfactory yields.

However, they have proven to be challenging because of the mutual inactivation of both catalysts. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 538-58-9
