Fig. 4: Controlled directional motion of Rh centre over increasing track length.
From: [1,n]-Metal migrations for directional translational motion at the molecular level
Controlled translational motion over longer length scales; polyaniline tracks 16 and 17 as substrates under the optimised reaction conditions with [RhCl(cod)]2 (10 mol%), dppp (20 mol%), norbornene (22 equiv.) giving hexa- and octa-substituted tracks as the major substitution products (hexa-16 and octa-17), respectively; for 16, isolated combined yield of tetra-16 and hexa-16; for 17, octa-17 identified as major component of reaction by MALDI HRMS (see Supplementary Information Section 3.10 for details); shades of green used to illustrate sequential incorporation of norbornene. Note that all incorporated norbornane units are depicted arbitrarily as (R, R, S).
