Mono‐reduced Corannulene: To Couple and Not to Couple in One Crystal

Autor: Andrey Yu. Rogachev, Melisa Alkan, Alexander S. Filatov, Sarah N. Spisak, Jingbai Li, Shuyang Liu, Marina A. Petrukhina

Publikováno v: Chemistry – A European Journal. 25:14140-14147

One-electron reduction of corannulene, C20 H10 , with Li metal in diglyme resulted in crystallization of [{Li+ (diglyme)2 }4 (C20 H10.- )2 (C20 H10 -C20 H10 )2- ] (1), as revealed by single-crystal X-ray diffraction. This hybrid product contains two

Placing Metal in the Bowl: Does Rim Alkylation Matter?

Autor: Jingbai Li, Marina A. Petrukhina, Andrey Yu. Rogachev, Qi Xu, Zheng Zhou, Sarah N. Spisak, Zheng Wei, Shuyang Liu

Publikováno v: Organometallics. 38:552-566

In-depth theoretical analysis of the consequences of methylation of the rim sites of corannulene is completed. The full set of derivatives ranging from parent C20H10 to fully substituted C20(CH3)10 has been evaluated, revealing consistent trends alon

Site‐Directed Dimerization of Bowl‐Shaped Radical Anions to Form a σ‐Bonded Dibenzocorannulene Dimer

Autor: Alexander V. Zabula, Marina A. Petrukhina, Sarah N. Spisak, Melisa Alkan, Andrey Yu. Rogachev, Alexander S. Filatov

Publikováno v: Angewandte Chemie International Edition. 57:6171-6175

Designed site-directed dimerization of the monoanion radicals of a π-bowl in the solid state is reported. Dibenzo[a,g]corannulene (C28 H14 ) was selected based on the asymmetry of the charge/spin localization in the C28 H14.- anion. Controlled one-e

Highly strained [6]cycloparaphenylene: crystallization of an unsolvated polymorph and the first mono- and dianions

Autor: Marina A. Petrukhina, Sarah N. Spisak, Evan R. Darzi, Zheng Wei, Ramesh Jasti

Publikováno v: Chemical Communications. 54:7818-7821

An X-ray diffraction study of [6]cycloparaphenylene (1), crystallized under solvent-free conditions, revealed a unique solid state structure with tight packing of individual molecules that minimizes empty internal space. The controlled chemical reduc
