Usage

General Description

R-5,5',6,6',7,7',8,8'-Octahydro-1,1'-bi-2-naphthyl phosphate, also known as OBPA, is a flame retardant chemical commonly used in the production of plastic and rubber materials. It is known for its high thermal stability and effectiveness at reducing the flammability of various products. However, concerns have been raised about the potential health and environmental impacts of OBPA, as it has been found to persist in the environment and bioaccumulate in organisms. Studies have also linked OBPA exposure to potential endocrine disruption and reproductive toxicity. As a result, there is increasing regulatory scrutiny and public concern regarding the use of OBPA in consumer products. Efforts to find safer alternatives to OBPA in flame retardant applications are ongoing.

Direct Interconversion of BINOL and H8-BINOL-Based Chiral Br?nsted Acids Using Single-Step Red/Ox Manipulations

A direct single-step hydrogenation of BINOL-based chiral phosphoric acids, N-triflyl phosphoramides, and disulfonimides to the corresponding H8-BINOL Br?nsted acids in excellent yields and chemoselectivities is described. In addition, the conditions for t

Facile and efficient enantioselective strecker reaction of ketimines by chiral sodium phosphate

A facile and efficient enantioselective Strecker reaction of ketimines catalyzed by a chiral alkali-metal salt has been developed. When 10 mol% BNPNa (BNP=1,1'-binaphthyl-2,2'-diylphosphate) prepared in situ and 10 mol% para-tert-butylortho-adamantylphenol (PBAP) were introduced into the reaction, up to 96% yield and up to 95% ee (ee=enantiomeric excess) were obtained. Both aliphatic and aromatic ketimines, especially sterically bulky cyclic ketimines derived from β-acetonaphthone, α-indanone, and α-tetralone were found suitable for this reaction. On the basis of the experimental results and previous reports, trimethylsilyl cyanide (TMSCN) was indicated to be the real reactive nucleophile despite the existence of PBAP, and a possible working model was proposed to explain the origin of the asymmetric induction. The facile availability of 1,1'-binaphthyl-2,2'-diylphosphoric acid (BNPH) and the simplicity of the procedure are beneficial for practical applications.
