Related Products of 50777-76-9, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.50777-76-9, Name is 2-(Diphenylphosphino)benzaldehyde, molecular formula is C19H15OP. In a patent, introducing its new discovery.
Amphiphilic polystyrene-poly(ethylene glycol) resin-supported chiral imidazoindole phosphines (PS-PEG-L?), (3R,9aS)-2-aryl-3-(2-dialkylphosphino)phenyltetrahydro-1H-imidazo[1,5-a]indol-1-one, bearing PPh2, P(t-Bu)2, and P(c-Hex)2 groups were designed and prepared with a view toward using them in aqueous heterogeneous asymmetric Suzuki-Miyaura biaryl coupling. The asymmetric coupling of 2-substituted 1-iodonaphthalenes and 2-substituted naphthalen-1-ylboronic acid took place in water under heterogeneous conditions in the presence of 10 mol% palladium of PS-PEG-L?-Pd complexes to give up to 94% ee of (S)-2,2?-disubstituted 1,1?-binaphthyls.
