Air and moisture stable para- and ortho-quinodimethane derivatives derived from bis-N-Heterocyclic olefins
Jana, Subhadip; Elvers, Benedict J.; Patsch, Sebastian; Sarkar, Pallavi; Krummenacher, Ivo; Nayak, Mithilesh Kumar; Maiti, Avijit; Chrysochos, Nicolas; Pati, Swapan K.; Schulzke, Carola; Braunschweig, Holger; Yıldız, Cem Bural (American Chemical Society, 2023)Herein we report the development of a new methodology for the synthesis of various quinodimethane derivatives under two-electron oxidation of bis-Nheterocyclic olefins linked by different pi-conjugated aromatic spacers. ... -
Assembly of NHC-stabilized 2-hydrophosphasilenes from Si(iv) precursors: a Lewis acid-base complex
Dhara, Debebrata; Mandal, Debdeep; Maiti, Avijit; Yıldız, Cem Burak; Kalita, Pankaj; Chrysochos, Nicolas; Schulzke, Carola; Chandrasekhar, Vadapalli; Jana, Anukul (Royal Society of Chemistry, 2016)NHC-stabilized 2-hydrophosphasilenes are obtained from 1,2-dihydro-2-chlorophosphasilanes as Si(iv) precursors by a NHC-assisted 1,2-elimination of HCl. The NHC-exchange of these compounds is demonstrated as a proof of ... -
Comment on "Disclosing Cyclic(Alkyl)(Amino)Carbenes as a One-Electron Reductant: Synthesis of Acyclic(Amino)(Aryl)Carbene-Based Kekulé Diradicaloids"
Maiti, Avijit; Elvers, Benedict J.; Bera, Sachinath; Lindl, Felix; Krummenacher, Ivo; Ghosh, Prasanta; Braunschweig, Holger; Yıldız, Cem B.; Schulzke, Carola (Wiley-VCH - Home, 2023)The authors would like to correct a misassignment of an EPR spectrum in the title paper (https://doi.org/10.1002/chem. 202104567). The authors of the original paper reported the one-electron oxidation of the ... -
Disclosing Cyclic(Alkyl)(Amino)Carbenes as a One-Electron Reductant: Synthesis of Acyclic(Amino)(Aryl)Carbene-Based Kekulé Diradicaloids
Maiti, Avijit; Elver, Benedict J.; Bera, Sachinath; Lindl, Felix; I-Krummenacher, Ivo; Krummenacher, Ivo; Ghosh, Prasanta; Yıldız, Cem Burak; Braunschweig, Holger; Schulzke, Carola; Jana, Anukul (Wiley, 2023)Herein we disclose cyclic(alkyl)(amino)carbenes (CAACs) as a one-electron reductant under the formation of a transient radical cation as indicated by EPR spectroscopy. Subsequently, the disclosed CAAC reducing reactivity ... -
NHC-stabilized 1-hydrosilaimine: Synthesis, structure and reactivity
Dhara, Debabrata; Vijayakanth, Thangavel; Barman, Milan Kr; Naik, Khevath Praveen Kumar; Chrysochos, Nicolas; Yıldız, Cem Burak; Boomishankar, Ramamoorthy; Schulzke, Carola (Royal Society of Chemistry, 2017)A facile, straightforward synthesis of N-heterocyclic carbene (NHC)-stabilized 1-hydrosilaimine starting from a silicon(iv)-precursor is reported. It has been employed for the addition of an O-H bond of water under ambient ... -
Realizing 1,1-Dehydration of secondary alcohols to carbenes: pyrrolidin-2-ols as a source of cyclic (Alkyl)(Amino)carbenes
Daş, Ayan; Elvers, Benedict J.; Nayak, Mithilesh Kumar; Chrysochos, Nicolas; Anga, Srinivas; Kumar, Amar; Rao, D. Krishna; Narayanan, Tharangattu N.; Schulzke, Carola; Yıldız, Cem Burak; Jana, Anukul (Wiley-VCH Verlag, 2022)Herein we report secondary pyrrolidin-2-ols as a source of cyclic (alkyl)(amino)carbenes (CAAC) for the synthesis of CAAC-Cu-I-complexes and cyclic thiones when reacted with Cu-I-salts and elemental sulfur, respectively, ... -
Reduction of 2-H-substituted pyrrolinium cations: the carbon-carbon single bond in air stable 2,2′-bipyrrolidines as a two-electron-source
Nayak, Mithilesh Kumar; Elvers, Benedict J.; Mandal, Debdeep; Das, Ayan; Ramakrishnan, Raghunathan; Mote, Kaustubh R.; Schulzke, Carola; Yıldız, Cem Burak; Jana, Anukul (Royal Society of Chemistry, 2023)Reduction of 2-H-substituted pyrrolinium cations via initially formed secondary radicals results in either dimerisation or H-abstracted products, while the outcome depends on the N-substituents. The resultant central ...
