Abstract: Alkyl groups can delocalize both the negative and positive charges through ion (charge)-induced dipole interaction with the polarizable alkyl groups. This charge induced polarization of the alkyl group to delocalize the charge is the origin… read more here.

DOI: 10.1021/acs.orglett.6b03428
Abstract: Two novel β-hexaalkylated porphycenes, i.e., 2,3,7,12,13,17- (HOT) and 2,3,6,12,13,16-hexaethylporphycenes (HIT) were introduced for the first time in porphycene chemistry. These were synthesized through McMurry coupling reactions of new isomeric unsymmetrically substituted triethylbipyrrole dialdehydes. The positional… read more here.

Abstract: 1 : 1 mixtures of aminomethylenehelicene (P)-tetramer and (M)-pentamer with terminal C16 alkyl groups in fluorobenzene showed structural changes between hetero-double-helices B and C and random-coils 2A. Figure-eight thermal hysteresis appeared when the solution was cooled and… read more here.

DOI: 10.1039/d5ra03716f
Abstract: We find there to be no significant difference between the inductive effects of four representative alkyl groups as determined by Hirshfeld charge analysis. The use of alkyl group electronegativity values shows no meaningful correlation with… read more here.
