Recently I am researching about LIGANDS; HYDROGENATION; STEREOSELECTIVITY; PHOSPHINES; OXIDATION; ALCOHOLS; ACID, Saw an article supported by the National Science CentreNational Science Centre, Poland [2012/07/N/ST5/02194]. Computed Properties of C7H5NO4. Published in BEILSTEIN-INSTITUT in FRANKFURT AM MAIN ,Authors: Kmieciak, A; Krzeminski, MP. The CAS is 62-23-7. Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid
New chiral regioisomeric gamma-hydroxyphosphine ligands were synthesized from alpha-pinene. The key transformation was the thermal [2,3]-sigmatropic rearrangement of allyldiphenylphosphinites, obtained from (1R,2R,4S,5R)-3-methyleneneoisoverbanol and (1R,2R,3R,5R)-4-methyleneneoisopinocampheol, to allylphosphine oxides. Hydroxy groups were introduced stereoselectively through a hydroboration-oxidation reaction proceeding from the less hindered site providing a trans relationship between the hydroxy and the phosphine substituents.
Computed Properties of C7H5NO4. Welcome to talk about 62-23-7, If you have any questions, you can contact Kmieciak, A; Krzeminski, MP or send Email.
