1,1′-diphenyl-1,1′-bicyclopropyl and 1,1′-diphenyl-1,1′-bicyclobutyl
Lam, Yu-Lin,Koh, Lip-Lin,Huang, Hsing-Hua
, p. 397 - 400 (1996)
The molecules of 1,1′-diphenyl-1,1′-bicyclopropyl, C18H18, and 1,1′-diphenyl-1,1′-bicyclobutyl, C20H22, each possess a crystallographic centre of symmetry. Both molecules adopt the trans conformation. The cyclop
Iron-Catalyzed Ring Expansion of Cyclobutanols for the Synthesis of 1-Pyrrolines by Using MsONH3OTf

The synthesis of 1-pyrrolines from cyclobutanol derivatives and an aminating reagent (MsONH3OTf) has been developed. This one-pot procedure achieves C–N bond/C═N bond formation via ring expansion. A series of 1-pyrroline derivatives are synthes
Nickel-Catalyzed Arylation/Alkenylation of tert-Cyclobutanols with Aryl/Alkenyl Triflates via a C - C Bond Cleavage
Wang, Zhen,Hu, Yuanyuan,Jin, Hongwei,Liu, Yunkui,Zhou, Bingwei
, p. 466 - 474 (2020/12/22)
Herein, we first present a nickel-catalyzed arylation and alkenylation of tert-cyclobutanols with aryl/alkenyl triflates via a C-C bond cleavage. An array of γ-substituted ketones was obtained in moderate-to-good yields, thus featuring earth-abundant nick
Regioselective Electrochemical Cyclobutanol Ring Expansion to 1-Tetralones
Petti, Alessia,Natho, Philipp,Lam, Kevin,Parsons, Philip J.

A mild electrochemical method for the regioselective preparation of 1-tetralones under environmentally friendly conditions from readily available cyclobutanols was developed. A series of aromatic- and heteroaromatic-fused 1-tetralones was accessed through ring expansion of the functionalized cyclobutanols via electrochemical generation of alkoxy radicals and intramolecular cyclization.
