“…Modi®cation of the original procedure [9] recently led to a semi-technical process which afforded racemic BINOL in high purity [10]; for its optical resolution various methods are available [11]. The most convenient procedure makes use of the different solubility of diastereomeric inclusion complexes formed with benzylcinchonidinium chloride and affords both enantiomers in 99% yield in enantiomeric purities of 99% and 96%, respectively [12].…”

“…Herein, we report the synthesis of F 4 BINOL and its application in the asymmetric sulfoxidation reaction. [12,13]). The coupling of Grignard or lithium derivatives 5 and 6 with 4 afforded the desired product 9 in less than 10% yield (Scheme 1a and b).…”

“…[17] Die oxidative Dimerisierung von Phenolen und Naphtholen ist eine Reaktion, die auf die Arbeit von Pummerer 1914 zurückgeführt werden kann, [18] in der die oxidative Kupplung von 2-Naphtholen mit Silberoxid oder Kaliumferricyanid als Einelektronen-Oxidationsmittel beschrieben wurde. Darauffolgend wurden analoge Reaktionen mit verschiedenen anderen Oxidationsmitteln entwickelt.…”
