In heterogeneous catalysis, the catalyst is in a different phase from the reactants. name: 1,5-Diphenylpenta-1,4-dien-3-one, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 538-58-9, name is 1,5-Diphenylpenta-1,4-dien-3-one. In an article£¬Which mentioned a new discovery about 538-58-9
Catalyst-Controlled Chemodivergent Synthesis of Spirochromans from Diarylideneacetones and Organoboronic Acids
A chemodivergent synthesis of two series of spirochromans depending on the catalytic system was developed. Starting from diarylideneacetones and organoboronic acids, asymmetric rhodium catalysis led to the enantioselective synthesis of 4,4?-disubstituted 2,2?-spirobichromans, while acid catalysis led to the formation of 4-substituted spirochroman-2,2?-chromenes. A plausible mechanism of the chemodivergent synthesis was proposed.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 538-58-9, help many people in the next few years.name: 1,5-Diphenylpenta-1,4-dien-3-one
