The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: (R)-2,2′,6,6′-Tetramethoxy-4,4′-bis(diphenylphosphino)-3,3′-bipyridine( cas:221012-82-4 ) is researched.Application of 221012-82-4.Zhang, Xi-Chang; Wu, Yan; Yu, Feng; Wu, Fei-Fei; Wu, Jing; Chan, Albert S. C. published the article 《Application of Copper(II)-Dipyridylphosphine Catalyst in the Asymmetric Hydrosilylation of Simple Ketones in Air》 about this compound( cas:221012-82-4 ) in Chemistry – A European Journal. Keywords: ketone hydrosilylation copper pyridylphosphine catalyst; secondary alc asym preparation. Let’s learn more about this compound (cas:221012-82-4).
A copper(II) salt/chiral dipyridylphosphine/PhSiH3 system (see scheme) acts as a very effective and practical catalyst for the asym. reduction of heteroaromatic and other types of ketones in air with good-to-excellent enantioselectivities (up to 94 %), giving many chiral alcs. that are intermediates for physiol. active compounds Remarkable temperature effects were observed for some heteroaromatic ketones.
As far as I know, this compound(221012-82-4)Application of 221012-82-4 can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
