Diamidocarbene-Based Thiele and Tschitschibabin Hydrocarbons: Carbonyl Functionalized Kekulé Diradicaloids
Autor: Biprajit Sarkar, Avijit Maiti, Debayan Jana, Anukul Jana, Prince Ravat, Shubhadeep Chandra, Sebastian Sobottka
Publikováno v: The Journal of Organic Chemistry. 86:16464-16472
Herein, we report diamidocarbene (DAC)-based Thiele and Tschitschibabin hydrocarbons, diradicaloids that contain four carbonyl/amido functional groups. The impact of two different π-conjugated spacers, p-phenylene vs p,p'-biphenylene, has been reali

Elvers, Pradeep Kumar Pal, Benson Joseph, Rina Sikari, Mithilesh Kumar Nayak, Avijit Maiti, Tejender Singh, Nicolas Chrysochos, Arumugam Jayaraman, Ivo Krummenacher, Jagannath Mondal, U. Deva Priyakumar, Holger Braunschweig, Cem B. Yildiz, Carola Schulzke, Anukul Jana
Publikováno v: Chemistry – A European Journal. 29
Herein, a new type of carbodicarbene (CDC) comprising two different classes of carbenes is reported; NHC and CAAC as donor substituents and compare the molecular structure and coordination to Au(I)Cl to those of NHC-only and CAAC-only analogues. The

Anionic Boron- and Carbon-Based Hetero-Diradicaloids Spanned by a p-Phenylene Bridge
Autor: Michael Moos, Holger Braunschweig, Bernd Engels, Fangyuan Zhang, Abhishake Mondal, Prince Ravat, Sakshi Mehta, Avijit Maiti, Moulika Bhattacharyya, Christoph Lambert, Anukul Jana, Ivo Krummenacher
Publikováno v: Journal of the American Chemical Society. 143:3687-3692
Herein we report the synthesis and characterization of anionic boron- and carbon-based Kekule diradicaloids spanned by a p-phenylene bridge. In contrast to Thiele’s hydrocarbon, a closed-shell singlet system, they show an appreciable population of

Acyclic diaminocarbene-based Thiele, Chichibabin, and Müller hydrocarbons
Autor: Anukul Jana, Shubhadeep Chandra, Biprajit Sarkar, Avijit Maiti
Publikováno v: Chemical Science
Thiele, Chichibabin and Müller hydrocarbons are considered as classical Kekulé diradicaloids. Herein we report the synthesis and characterization of acyclic diaminocarbene (ADC)-based Thiele, Chichibabin, and Müller hydrocarbons. The calculated si

Direct access to 2-aryl substituted pyrrolinium salts for carbon centre based radicals without pyrrolidine-2-ylidene alias cyclic(alkyl)(amino)carbene (CAAC) as a precursor
Autor: Sebastian Sobottka, Biprajit Sarkar, Pankaj Kalita, Ramapada Dolai, Debabrata Dhara, Debdeep Mandal, Avijit Maiti, Anukul Jana, Vadapalli Chandrasekhar, Ramakirushnan Suriya Narayanan
Publikováno v: Chemical Science. 10:4077-4081
The synthesis of organic radicals is challenging due to their inherent instability. In recent years, cyclic(alkyl)(amino)carbene (CAAC)-derived 2-substituted pyrrolinium salts have been used as synthons for the synthesis of isolable carbon-based radi

We report the influence of N-heterocyclic carbenes (NHCs) on the hydrolysis of a diphosphene TerPPTer (1; Ter = 2,6-Mes2C6H3; Mes = 2,4,6-Me3C6H2), a phosphorus-analogue of an alkene. The diphosphene 1 itself is completely inert towards water. Howeve
