Poly(1-chloro-oct-1-yne): a new, high-molecular-weight polyacetylene synthesized with molybdenum catalysts

Abstract

1-Chloro-oct-1-yne polymerizes in the presence of Mo catalysts [e.g., MoCl₅, MoCl₅–Buⁿ₄Sn, Mo(CO)₆–CCl₄–hν] to give a new, high-molecular-weight (M_w up to × 10⁶), white, soluble, air-stable, electrically insulating poly-polyacetylene, which is the first example of a polymer from a chlorine-containing aliphatic disubstituted acetylene.
