Previous work has been done on substituent effects on the ionization equilibrium: Ar3CCl <-SO2-> Ar3C+Cl-, and the effect of the cyclopropyl group was compared to that of the other substituents studied. The cyclepropyl group is intermediate to a vinyl and an alkyl group in its ability to conjugate with adjacent unsaturation. It donates electrons readily but does not accept them as does an allyl group. Conjugation takes place between a cyclopropyl group and an ethylenic linkage, a ketone, phenyl or pyridyl group. The dipole moment and UV absorption wavelengths of the cyclopropyl group are intermediate to an allyl and an alkyl group. [TRUNCATED] / 2031-01-01
