Research speed reading in 2021. Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 99-14-9, Name is Propane-1,2,3-tricarboxylic acid, SMILES is O=C(O)CC(CC(O)=O)C(O)=O, in an article , author is RODRIGUEZMORGADE, S, once mentioned of 99-14-9, Quality Control of Propane-1,2,3-tricarboxylic acid.
The reaction of [2,1]benzisoxazole-4,7-quinones 1 and naphth[2,3-c]isoxazole-4,9-quinone 4 with phosphines leads to phosphoranylideneaminoquinones 2 and 5, respectively, in good to excellent yields.
