“…Increasing reaction times and temperatures did not affect this outcome. A telescope procedure from 1 to 32 was also attempted using 4 equiv of benzyl bromide similar to procedures outlined by Levashova et al; 41 HMTA salt 3 and multiple degradation products were detected by LCMS analysis over a 2 h heating period at 60 °C. Furthermore, it is unclear whether hydrolysis of a compound such as 32 would hydrolyze cleanly to compound 4 or whether it would break down into a multitude of alkyl amino fragments instead as were observed by LCMS during the attempted synthesis.…”

Herein, we report our efforts to improve the sustainability of the Delépine reaction for the formation of primary amines from activated alkyl halides. A number of alternative greener, more sustainable solvents to the traditionally employed chloroform were identified, and the use of dimethyl carbonate (DMC) as a solvent was exemplified in the synthesis of a number of pharmaceutically relevant building blocks including the 40 mmol scale synthesis of N-Boc-3-pyrroline. Green chemistry metrics were calculated to identify areas of the Delépine reaction that could potentially be improved upon. Poor atom economy (A.E.) was identified as a key shortcoming of this methodology, although our efforts to improve A.E. and reduce waste were unfortunately unsuccessful. A preliminary thermal safety evaluation was conducted using differential scanning calorimetry due to stability concerns raised over the nature of the products; none of the products were considered to have shock-sensitive or explosive propagating properties. The limits of potential sustainability improvements that could be achieved are critically discussed including the inherent issues with this methodology such as the release of formaldehyde, generation of carcinogenic bis(chloromethyl)ether, and poor atom economy.

This work presents a detailed study on the effect of various functional groups both at the ortho position of the aromatic ring and in the amino group of PANI on the antibacterial properties of polymers against gram-positive (Bacillus subtilis) and gram-negative (Pseudomonas aureofaciens) microorganisms. It was found that incorporation of methyl, methoxy, or pentyl groups into the orthoposition of PANI did not increase the antibacterial activity but in most cases causes a significant decrease in the antibacterial properties of functionally substituted polyanilines. At the same time, PANI derivatives modified by incorporation of pentyl groups into the amino group were found to be more efficient antibacterial compounds against both gram-positive and gram-negative microorganisms than the original polymer. It was also found that N-substituted PANI derivatives manifest not only bactericidal but also bacteriostatic properties toward the test microorganisms. Varying the nature and position of the substituent allowed us to conclude that the synthesis of various N-substituted PANI derivatives with a high degree of doping is the most promising approach to PANI modification for application in bacterial growth inhibition.
