1,6-Heptadiyne, 97%, Thermo Scientific Chemicals

Description

1,6-Heptadiyne may be used in the preparation of free-standing polymer films of poly(1,6-heptadiyne). Polymerization of 1,6-heptadiyne using an insoluble Zeigler-Natta catalyst affords soluble polymer having six-membered ring containing polyene. Ruthenium(II)-catalyzed reaction of a substituted 1,6-heptadiyne with norbornene affords a tandem [2+ 2+ 2]/[4+2] cycloaddition product and a [2+ 2+2] cycloadduct.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
