An air-stable n-type bay-and-headland substituted bis-cyano N-H functionalized perylene diimide for printed electronics

The synthesis of 6,11-bis-cyano N-H functionalized perylene diimide is reported. Electron withdrawing cyano groups were installed to counter the electron donating cyclic amine moiety with retention of functionality. Solution-processed, air-stable...

Acid and base strength variations: rationalization for cyclic amine bases and acidic aqua cations

Recent experimental and theoretical results for the title compounds are critically examined by means of interlinked thermodynamic cycles and observed trends in acid and base strength rationalized by using changes in simple chemical concepts.

Synthesis and Properties of N1-(indan-5-yl)amidrazones Incorporating Piperazines and Related Congeners

: A selected set of new N1-(indan-5-yl)amidrazones 4a-p, encompassing piperazines or related amines, has been prepared via interaction of the hydrazonoyl chloride 3 (derived from 5-aminoindane) with the appropriate sec-cyclic amine in the presence of triethyl amine. Their suggested structures are supported by IR, 1H NMR, 13C NMR, high resolution MS (ESI) spectral data and further confirmed by single-crystal X-ray crystallography for 4k. These novel compounds were screened for their antitumor activity against breast cancer cells (MCF7 and T47D); amongst all of them, only compound 4o, incorporating N-(pyrimidin-2-yl)piperazine, was fairly active with IC50 values of 69 µM and 61 µM, respectively.

POP-Pd(ii) catalyzed easy and safe in situ carbonylation towards the synthesis of α-ketoamides from secondary cyclic amines utilizing CHCl3 as a carbon monoxide surrogate

POP-palladium(ii) was synthesized for the in situ carbonylation of aryl iodides and secondary cyclic amine to the respective α-ketoamides.

Fragment-oriented synthesis: β-elaboration of cyclic amine fragments using enecarbamates as platform intermediates

Selective β-sp3 functionalisation of cyclic amines is achieved through enecarbamate formation and photoredox-catalysed derivatisation with functionalised alkyl halides.

Polysiloxane-containing epoxyurethane oligomers and coatings on their basis

The influence of organosilicon rubber on the properties of an epoxy-urethane oligomer cured with a cyclic amine was studied. The physicomechanical characteristics of binders are determined. It is shown that the modification of the epoxyurethane resin with organosilicon leads to an increase in the values of the physicomechanical characteristics and the glass transition temperature of the binders.
