Delocalized carbon-based radical species with unpaired spin, such as the phenalenyl (PLY) radical, have opened avenues for developing multifunctional organic spintronic devices. Using direct laser writing and in situ deposition, we successfully fabri

Mechanochemical solid state single electron transfer from reduced organic hydrocarbon for catalytic aryl-halide bond activation

Autor: Amit Biswas, Anup Bhunia, Swadhin K. Mandal

Publikováno v: Chemical Science. 14:2606-2615

Under the influence of mechanical energy, a reduced organic hydrocarbon can transfer electrons in the solid-state to accomplish strong bond activation. Such activation was integrated into a catalytic cycle to design cross-coupling reactions.

Bicyclic (alkyl)(amino)carbene (BICAAC) in a dual role: activation of primary amides and CO2 towards catalytic N-methylation

Autor: Nimisha Gautam, Ratan Logdi, Sreejyothi P., Antara Roy, Ashwani K. Tiwari, Swadhin K. Mandal

Publikováno v: Chemical Science. 14:5079-5086

This work reports the first catalytic N-methylation of primary amides using CO2. BICAAC plays a dual role in activating the amide and CO2 during catalysis.

Phenalenyl Radical: Smallest Polycyclic Odd Alternant Hydrocarbon Present in the Graphene Sheet

Autor: Jasimuddin Ahmed, Swadhin K. Mandal

Publikováno v: Chemical Reviews. 122:11369-11431

Phenalenyl, a zigzag-edged odd alternant hydrocarbon unit can be found in the graphene nanosheet. Hückel molecular orbital calculations indicate the presence of a nonbonding molecular orbital (NBMO), which originates from the linear combination of a

Regioselective ring-opening of epoxides towards Markovnikov alcohols: a metal-free catalytic approach using abnormal N-heterocyclic carbene

Autor: Sreejyothi P., Pallavi Sarkar, Supriti Dutta, Arpan Das, Swapan K. Pati, Swadhin K. Mandal

Publikováno v: Chemical Communications. 58:9540-9543

Herein we report the first metal-free regioselective Markovnikov ring-opening of epoxides (selectivity up to 99%) using an abnormal N-heterocyclic carbene (aNHC) to yield secondary alcohols. DFT calculations and X-ray crystallography suggest that the
