✦ Synopsis

A new method for the preparation of oligo(1,4-phenylene ethynylene)s is described. Only two sets of reaction conditions are needed for the entire iterative synthetic sequence: (1) Pd-catalyzed cross-coupling of trirnethylsilylacetylene with an aryl halide and (2) in situ desilylation/Pd-catalyzed coupling with an aryl iodide. This method provides a fast synthetic route to short length oligo(1,4-phenylene ethynylene)s by oligomer growth at both ends.

## Abstract The novel double‐stage convergent synthesis of a new class of polyisoprene terpenoid (PIPTP) dendrons is described. PIPTP dendrons bear a highly branched aliphatic hydrocarbon skeleton and a hydrophilic hydroxy focal point functionality. These dendrons have the specific formula C~(5Γ—2~^
