Screw‐Sense‐Selective Polymerization of Isocyanides by Dinuclear μ‐Ethynediyl Complexes

Single-handed helical polymers of the type 2 are the products of the screw-sense-selective polymerization of achiral isocyanides ArNC initiated by the helical oligomer complexes 1. The latter are accessible from μ-ethynediyl-bridged dinuclear Pd,Pt complexes by reaction with 3-CNC6H4CO2R* (R* = (+)- and (-)-menthyl).
