Fig. 1: Summary of C–C coupling reactions involving two cations R1a, R1b for carbon chain elongation (CCE).

a The schematic illustration on the initial stage (d0 》2d1) of two positively charged acetone cations, R1a, R1b, approaching each other. b The repelling and coupling stage (d2 < d0 < d1) of two positively charged acetone cations, R1a, R1b, approaching to each other. c The investigated C–C coupling reactions between two positively charged molecules, R1a, R1b. Note: R1a, R1b: two sodiated acetone. d0 is the distance between the two positive charges sitting on the carbonyl carbon atoms of R1a and R1b. d1 is the effective radius of the reaction cross-section between R1a and R1b. d2 is the average length of C–C bond.
