possible to prepare polyacetylene or shorter oligomers in a controlled polymerization of acetylene. There is good evidence that this should be possible under the right circumstances by using an alkylidene complex (eq 1). The authors report here the preparation of livingpolyenes of moderate length and block copolymers containing polyene sequences by this method.
