Lipshutz, Bruce H.; Noson, Kevin; Chrisman, Will; Lower, Asher published the artcile< Asymmetric Hydrosilylation of Aryl Ketones Catalyzed by Copper Hydride Complexed by Nonracemic Biphenyl Bis-phosphine Ligands>, Electric Literature of 112-63-0, the main research area is copper hydride diphosphine catalyst asym hydrosilylation reduction aromatic ketone; ketone aromatic asym hydrosilylation reduction chiral benzyl alc preparation; silane hydrosilane reduction aromatic ketone asym copper diphosphine catalyst.
Copper hydride is an extremely reactive catalyst capable of effecting asym. hydrosilylations of aromatic ketones at temperatures between -50 and -78°, when complexed by chiral diphosphines of the BIPHEP or the SEGPHOS series. Inexpensive silanes serve as stoichiometric sources of hydride. Substrate-to-ligand ratios exceeding 100,000:1 were achieved. The level of induction is usually in the >90% ee category. The nature of the reagent was investigated using spectroscopic and chem. means, although its exact structure remains unclear.
Journal of the American Chemical Society published new progress about Aralkyl alcohols Role: SPN (Synthetic Preparation), PREP (Preparation). 112-63-0 belongs to class esters-buliding-blocks, and the molecular formula is C19H34O2, Electric Literature of 112-63-0.
