Let’s face it, organic chemistry can seem difficult to learn. Especially from a beginner’s point of view. Like 4395-98-6, Name is 4-Cyanopiperidine. In a document, author is Beckett, Michael A., introducing its new discovery. Category: piperidines.
Amine adducts of (4-ClC6H4)(3)B3O3, Lewis acidity of triarylboroxines, and an XRD study on the related tetraphenylboroxinate(1-) salt, [C6H11NMe3][Ph4B3O3]
The stoichiometric reactions of amines with tri(4-chlorophenyl)boroxine (CPB) led to the formation of adducts CPB center dot L {L – morpholine (1a), benzylamine (1b) cyclohexylamine (1c), 2-picoline (1d), 4-picoline (1e), piperidine (1f)} and (CPB)(2)center dot(4,4′-trimethylenedipiperidine) (1g). Compounds 1a-1g have been characterized by NMR (B-11, H-1, C-13), IR spectroscopy and powder-XRD. VT H-1 NMR spectra on 1a and 1d-1g were consistent with a ligand exchange/recombination process and activation energies of 49-58 kJ mol(-1) were obtained. The synthesis of [C6H11NMe3][Ph4B3O3] (2) from Ph2BOBPh2, PhB(OH)(2) and [C6H11NMe3][OH] in a 1:4:2 ratio in MeOH/H2O is also reported. Compound 2 was characterized by thermal analysis (TGA/DSC), spectroscopy (IR, NMR) and 1a, 1b and 2 were further characterized by single-crystal XRD studies. (C) 2018 Elsevier B.V.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 4395-98-6 help many people in the next few years. Category: piperidines.
