examined the gas-phase unimolecularrearrangements of a series of substituted cyclopropyl anions (CHXCH 2 CY - ; X=H, Y=Ph, CHO, and CN; X=Y=CO 2 CH 3 ) with a variable temperature flowing afterglow device. The ring-opening barriers range from 19 to ≥36 kcal mol -1 and are well reproduced by ab initio molecular orbital calculations.An analysis of eight monosubstituted cyclopropyl anions reveals that the
