Improved Schmidt Conversion of Aldehydes to Nitriles Using Azidotrimethylsilane in 1,1,1,3,3,3-Hexafluoro-2-propanol.
The Schmidt reaction of aromatic aldehydes using a substoichiometric amount (40 mol %) of triflic acid is described. Low catalyst loading was enabled by a strong hydrogen-bond-donating solvent hexafluoro-2-propanol (HFIP). This improved protocol tolerates a broad scope of aldehydes with diverse functional groups and the corresponding nitriles were obtained in good to high yields without the nee...
متن کامل1,1,1,3,3,3-Hexafluoro-2-propanol and 2,2,2-trifluoroethanol solvents induce self-assembly with different surface morphology in an aromatic dipeptide.
Peptide based self-assembled structures, especially those from smaller peptides, have attracted much research interest due to their potential applications as biomaterials. These structures have been produced using different solvents (one of the methods), including alcohols, except fluorinated alcohols, which are believed to support non-aggregated structures. Herein, we have studied the ability ...
متن کامل1,1,1,3,3,3-Hexafluoro-2-propanol (HFIP) as a novel and effective solvent to facilely prepare cyclodextrin-assembled materials.
We found that cyclodextrins (CDs) have a high solubility in 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP). Evaporating HFIP from CD solutions on a glass plate gave crystalline solids composed of channel-type CD assemblies, and electrospinning with an HFIP solution of CDs fabricated CD microfibers.
متن کاملNMR structures of the C-terminal segment of surfactant protein B in detergent micelles and hexafluoro-2-propanol.
Although the membrane-associated surfactant protein B (SP-B) is an essential component of lung surfactant, which is itself essential for life, the molecular basis for its activity is not understood. SP-B's biophysical functions can be partially mimicked by subfragments of the protein, including the C-terminus. We have used NMR to determine the structure of a C-terminal fragment of human SP-B th...
متن کامل(3-Aminophenyl)diphenylphosphine oxide–2-propanol (1/1)
The title compound, C(18)H(16)NOP·C(3)H(8)O, was synthesized by the reduction of (3-nitro-phen-yl)diphenyl-phosphine oxide in the presence of 2-propanol as recrystallization solvent. There are two molecules in the asymmetric unit. Each P atom is tetra-coordinated by three C and one O atom from two phenyl fragments, one aniline group and one double-bonded O atom in a distorted tetra-hedral geome...
