On October 9, 2013, Garner, A. Christopher; Hodgkinson, Roy C.; Wallis, John D. published an article.Application In Synthesis of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate The title of the article was Menthyloxycarbonyl phosphonium chlorides: new derivatives for determining the enantiomeric excess of chiral tertiary phosphines. And the article contained the following:
The direct alkoxycarbonylation of tertiary phosphines with alkyl chloroformates was examined and the products characterized by NMR and x-ray crystallog. anal. The derivation of representative chiral tertiary phosphines with enantiopure menthyl chloroformate allows the determination of the enantiomeric excess of scalemic mixtures by 31P NMR spectroscopic anal. The experimental process involved the reaction of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate(cas: 14602-86-9).Application In Synthesis of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate
