Structure of Cyclopropane [PDF]
Nature, 1947 DR. Walsh has defended his suggested structure1 for the compounds ethylene oxide and cyclopropane in terms of a molecular orbitals picture based on the assumption that the carbon atoms are in the trigonal, or near-trigonal, state. The calculations by Linnett2 of the CH-bond force-constants are consistent with trigonal bonding.

Synthesis of (Het)aryl 2-(2-hydroxyaryl)cyclopropyl Ketones
Molecules, 2020 A simple general method for the synthesis of 1-acyl-2-(ortho-hydroxyaryl)cyclopropanes, which belong to the donor–acceptor cyclopropane family, has been developed.

Trifunktionelle Cyclopropane als Vorstufen von Triafulven und Calicen
CHIMIA, 1981 A series of 1,1-dihalo-2-X-cyclopropanes 3 have been prepared and characterised. Cyclopropanes of type 3 could be of interest as starting materials with respect to the attempted synthesis of triafulvene and calicene.

Copper‐Catalyzed Enantio‐ and Diastereoselective Addition of Silicon Nucleophiles to 3,3‐Disubstituted Cyclopropenes [PDF]
, 2019 A highly stereocontrolled syn‐addition of silicon nucleophiles across cyclopropenes with two different geminal substituents at C3 is reported. Diastereomeric ratios are excellent throughout (d.r.≥98:2) and enantiomeric excesses usually higher than 90 ...
